SUPPLEMENTAL COOLANT HEATING FOR FUEL CELLS WITH METAL PLATES |
摘要 |
A fuel cell stack that includes catalyzed surfaces in the non-active inlet region of the cathode flow channels. At cold system start-up, hydrogen is introduced into the cathode inlet header to be mixed with air so that a chemical reaction is provided by the catalyst that generates heat to warm the cooling fluid in the non-active inlet area. Therefore, the cooling fluid that enters the active area of the stack will not be cold enough to quench the chemical reaction.
