A stack ( 11 ) of fuel cells have water flow channels receiving water through a pump ( 33 ) from an accumulator ( 29 ) having double walls ( 63, 66 ) with vacuum insulation panels (VIPs) ( 65, 68 ) therebetween, auxiliary DC power source ( 80 ) (battery or supercapacitor) is disposed in a container ( 43 ) having double walls ( 81, 86 ) with VIPs ( 65, 68 ) encapsulated therebetween. A keep-warm heater ( 51 ) keeps the source warm enough for at least half power capacity, the source driving its own heater as well as a keep-warm heater ( 50 ) in the accumulator to keep the accumulator above freezing. A microwave heater ( 58 ) disposed in the accumulator distributes energy to melt ice using fuel cell stack power upon startup. |
