INTRODUCTION Tropical‟s hydrogen fuel cell power system, “TB-1000”, is a DC unregulated power system based on PEM (Proton Exchange Membrane) fuel cell technology. The system has to be fuelled with pure hydrogen and it is capable to deliver up to 1,4kWe electrical power peak and 1,2kWe in nominal continuous power condition.

The system is totally automated, driven by its own Tropical‟s control unit. Other data communication interface as RS232 and Ethernet are available as optional. The Ballard‟s FCgen1020ACS fuel cell stack module thanks to its extremely high power density is specifically designed where the space available is a critical issue. The architecture of the whole system is based on an extreme tough integration of the stack with the balance of plant and electronics (power & control).

The TB-1000 is equipped with the state of the art of control electronics and sensing system for voltage current and hydrogen detection. All the electronics and sensors have an intelligent protocol interface (with a microprocessor) for an extremely safe and reliable communication and data exchange. The TB-1000 is the core component and together the complementary inverter or the DC/DC converter or the battery charger is the right solution for most of the market needs.

GENERAL DESCRIPTION TB-1000 fuel cell power system is a fully automated system that produces unregulated DC power from a supply of hydrogen and air, using a low temperature PEM fuel cell stack. All required peripherals are included on this system as well as numerous onboard metering and safety sensors that monitoring the whole system at any time.

A large touch screen monitor is included on TB-1000, where all the data as well as the parameters can be seen & recorded on a flash usb stick at time intervals that are set by the user; therefore there is no need for a close by computer. TB-1000 also incorporates operational safety systems for indoor operation for educational and laboratory usage.

MICROPROCESSOR CONTROLLING SYSTEM TB-1000 system operation is automated by an electronic control system. The control board receives various input signals from onboard sensors. Input signals to the control board include: fuel cell stack temperature, hydrogen pressure, hydrogen leak percentage, fuel cell stack current, fuel cell stack voltage and hydrogen consumption.

Analogue and digital output control signals are issued from the control board to regulate system operation. Control commands are issued for opening and closing the hydrogen solenoid valve and purge valve. The speed of the air / cooling fan is varied based on current demand. The speed of the cooling fan is also controlled to regulate the fuel cell stack temperature. An external load relay is opened or closed by the control system for engaging or disengaging the fuel cell stack to external loads.

The control system also issues a signal for opening and closing external solenoid valves, to isolate hydrogen storage tanks when the system is not in operation. Communications to and from the end product are made via the touch screen monitor and an usb flash disk for recording transmitted data. Data transmitted from the control board includes several operational parameters which are listed on a later chapter. Any unusual or unsafe operating conditions result in an alarm and automatic shutdown, depending on severity.

During any warning, the fuel cell system continues to operate and the controller attempts to remedy the condition. During an alarm, the controller initiates a controlled shutdown sequence. Removing the external on/off signal will reset most alarms. For safety reasons, certain alarms can only be reset by Tropicalâ&#x20AC;&#x;s Customer Service. These nonrestartable faults include hydrogen leaks, self-test faults and software faults.

TOUCH SCREEN MONITOR The touch screen monitor operates on Windows CE and there are four regions/lines of operation, which are: a)

The upper region/line, where it states the software‟s version, time and date

The schematic region/line, where there is a schematic of the whole system and certain data is presented for the user

The alarm / warning region/line, where any alarms occur are presented on real time operation

Moreover, data for all the systems and subsystems is presented on real time basis. c) The alarm/warning region/line On this line any alarm or warning occurred on the fuel cell system will be shown on the user. If there is no alarm or warning, the line will be green and it will state “System OK and running” d) The lower region/line On this line appeared five buttons, each one of it enables new screens which are presented on the following paragraphs:

Start/Stop Button When this button is pressed, the user gives the command to the controller to start or stop the fuel cell system at any time.

Alarms Button By pressing the Alarm Button, the user can see on a new screen all the alarms and warnings that have been recorded up to this point

System Button When you press the System Button, asks you for a 4 digit password. By entering the password, the user arrives to the screen beside, where he can edit any parameter from the controller (even while it is on operation the system)

SAFETY SYSTEMS TB-1000 has automatic provisions to ensure operator safety and prevent equipment damage. A warning or alarm occurs when an unusual or unsafe operating condition occurs, depending on severity. During a warning, the power module continues to operate and the controller attempts to remedy the condition. During an alarm, the controller initiates a controlled shutdown sequence. The TB-1000 power system employs the following monitoring and shut down mechanisms to ensure safe fuel cell operation is maintained at all times:  Fuel cell operating parameters are continuously monitored to ensure they stay within desired limits. These include fuel cell stack operating temperature, fuel cell stack current, output voltage, fuel supply pressure and hydrogen consumption. Warnings and shut down alarms are implemented on each of these parameters  A hydrogen leak detector is implemented within the fuel delivery subassembly. This sensor can also detect excessive hydrogen purge amounts or the presence of an external fuel leak in the fuel cell stack. The system will shut down automatically if a hydrogen leak is detected.  Air filter can be safely providing protection for a certain period of time; therefore after a given amount of time, an alarm informs the user that all the filters need to be replaced.

In addition to warnings and alarms, other safety features are included to the design of TB-1000:  A fuel shutoff solenoid valve closes whenever the power module is shut down. This isolates the fuel supply and prevents hydrogen from entering the fuel cell stack in the event of an alarm shutdown.  Under normal operation, hydrogen released by way of the purge solenoid valve mixes with the cooling air stream, where it quickly diffuses and dilutes. This eliminates the potential formation of a flammable gas mixture in the cooling air flow and permits indoor operation.  A pressure relief valve discharges hydrogen during overpressure conditions to protect the fuel cell stack from damage. When the relief valve opens, the hydrogen concentrations measured exceed the hydrogen sensor alarm setting, and the power module shuts down.

OPERATION The TB-1000 fuel cell system provides fully automated operation and load response. In order to operate the unit, one must provide only adequate hydrogen fuel supply according to the specifications and the system is ready for start up.

! ATTENTION: Inlet H

Pressure must never be higher than 2bar and must always be regulated

Once this step is taken, the TB-1000 will export unregulated DC electric power on demand after pressing the start button. On the following paragraphs, certain steps for proper operation are explained in detail.

START UP PROCEDURE 1. We supply Hydrogen (Grade 4 – 99.99%) to the system and please note that the hydrogen’s pressure must never exceed 2bar. Note 1. For safety reasons a pressure relief valve has been installed on the system in case hydrogen with more than 4bar pressure is supplied. Note 2. A miniature pressure regulator keeps the hydrogen pressure stabilized at 1.3bar (miniature pressure regulator Input range is 0-2bar). 2. By pressing the green START BUTTON on TB-1000 front panel, provides power to the onboard control system, on the metering devices / sensors which are checking that there are no system faults as well as on the LCD touch screen monitor which opens the main screen. 3.
