High cost of operation and maintenance is the major factor restraining growth of the Regenerative Fuel Cell (RFC) Technologies Regenerative fuel cell (RFC) systems produce power and electrolytically regenerate their reactants using stacks of electrochemical cells. When a fuel cell is operated in reverse, the anode becomes the cathode and the cathode becomes the anode. Supplying a current and reversing the polarities of the electrodes in the hydrogen fuel cell results in a regenerative hydrogen fuel cell. The anode oxidizes water decomposing it into oxygen gas O2, hydrogen ions and electrons. The cathode reduces hydrogen and electrons into hydrogen gas. Such type of energy storage systems with extremely high specific energy have been designed that use lightweight pressure vessels to contain the gases generated by reversible regenerative fuel cells (URFCs). A regenerative fuel cell uses oxygen and hydrogen for the production of water, electricity, and waste heat. This type of fuel cell can store extremely high specific energy as compared to the other fuel cells such as methanol fuel cell, polymer electrolyte membrane (PEM) cell, and others. According to the U.S. Department of Energy, the packed specific energy in RFC is up to 1,000 W-hr/Kg whereas that of nickel/cadmium (Ni/Cd) and Lithium ion (Li/ion) batteries is less than 100 W-hr/Kg. In a regenerative fuel cell, the conversion of fuel cell reactants into products and reconversion of fuel cell products into reactants are the two stages involved in the process of producing electrical energy. Increasing adoption of RFC by various end-use industries due to its wide applications is a major factor fueling growth of the regenerative fuel cell technology market. RFC has various applications such as it can store energy for remote off-grid power sources, emergency or backup power generation, emergency or backup power generation, high-altitude, long-endurance solar rechargeable aircraft, and hybrid energy storage/propulsion systems for spacecraft. However high cost of operation and maintenance is the major factor restraining growth of the Regenerative Fuel Cell (RFC) Technologies market. Read More@ https://bit.ly/3nd06qj
