Abstract
This application relates to a system and method for regulating the temperature of a self-contained fuel cell apparatus preferably comprising a fuel reformer. The invention maintains the various components of the fuel cell apparatus within preferred operating temperature ranges while ensuring that exhaust gases and external surfaces of the apparatus do not exceed safe temperature levels. The invention is particularly suited for self-contained hybrid power supply applications, for example for non-road electric vehicles. The various components of the apparatus are strategically configured relative to air flow paths to fully utilize the cooling capacity of the process stream and minimize parasitic loads. In some embodiments the inlet air is pre-heated to enable operation of the apparatus in low temperature environments, such as industrial freezers.
