Abstract
A solid oxide fuel cell stack includes a core region which comprises a plurality of first modules and a plurality of second modules stacked alternately. Each first module comprises a first distribution member formed from two corrugated ceramic plates which define 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 formed from two corrugated ceramic plates which define internal passages for the supply of a second reactant to the fuel cells. A plurality of passages are defined between the fuel cells and the second distribution member which distribute and remove the second reactant from the cathodes.
