ABSTRACT:
A solid oxide fuel cell stack comprises a plurality of first modules and a plurality of second modules stacked alternately. Each first module comprises a first distribution member which defines internal passages for the supply of a first reactant to the fuel cells. The first distribution member is enclosed by a porous support structure which carries the fuel cells on its two parallel surfaces. A plurality of passages are defined between the porous support structure and the first distribution member which distribute and remove the first reactant from the anodes. Each second module comprises a second distribution member which defines internal passages for the supply of a second reactant to the fuel cells. The passages in the first distribution member contain a catalyst for steam reforming the fuel. The catalyst is in intimate thermal contact with the fuel cells. Additionally a low temperature adiabatic preformer supplied with hydrocarbon fuel prereforms the fuel and supplies it to the passages.
