Regenerative Fuel Cell System For Renewable Energy Facilities

Development of a regenerative fuel cell/electrolyzer is proposed. GES will size two of their advanced technologies; a high-pressure electrolyzer that can directly fill hydrogen and oxygen storage vessels up to 3000 psi; and a dead-ended fuel cell that can use these gases directly and remove the product water without recirculating the feed gases. Combined these two technologies lead to a great system simplification over traditional regenerative fuel cell systems. Performance of the dead-ended fuel cell will be demonstrated at the appropriate scale and a cost/benefit analysis will be conducted to size the system components. Successful completion of this program will result in proven fuel cell and electrolyzer components at the appropriate size as well as a system design to incorporate them in a 500-kW system to be used for interruption in renewable energy sources.
