Cooling system for a burst power fuel cell

摘要

Spaced based burst power fuel cells generate large thermal loads in very short time periods. In order to avoid external venting or the use of heavy radiators in space vehicles, such fuel cells must include onboard closed-loop cooling systems. Utilizing subcooled ice as a cooling medium, contactable with either the anode, cathode or coolant recirculating stream provides the fuel cell with a safe, highly efficient and low weight heat absorption capability.
