Abstract
A fuel cell comprises a reformer interposed between a fuel electrode and an oxidant electrode and having a preheating zone and a reforming zone in which a reforming catalyst is laid. Fuel gas introduced into the fuel is at first introduced into the preheating zone where it is preheated by heat generated during power generation.
Claims14
A fuel cell comprising a cell body having at least one cell element mainly composed of a fuel electrode and an oxidant electrode and an electrolyte board interposed between said fuel electrode and said oxidant electrode, and a plate-type reformer incorporated adjacent to said cell body, said reformer having a zone for preheating fuel gas and a reforming zone in which a reforming catalyst is located, said preheating zone being located upstream of said reforming zone in a direction in which said fuel gas flows, and including fins for radiating heat transmitted from said fuel cell so as to preheat said fuel gas.
A fuel cell comprising a cell body having at least one cell element mainly composed of a fuel electrode and an oxidant electrode, and an electrolyte board interposed between said fuel electrode and said oxidant electrode, and a plate-type reformer incorporated adjacent to said cell body, said reformer having a preheating zone and a reforming zone in which a reforming catalyst is located, and said preheating zone being located upstream of said reforming zone and including a heat-exchanging filler for transmitting heat from said cell element so as to heat said fuel gas.
