Ein Festoxid-Brennstoffzellenstapel

摘要

A solid oxide fuel cell stack (10) includes a core region (12) which comprises a plurality of first modules (24) and a plurality of second modules (26) stacked alternately. Each first module (24) comprises a first distribution member (28) formed from two corrugated ceramic plates (32,34) which define internal passages (30) for the supply of a first reactant to the fuel cells (22). The first distribution member (28) is enclosed by a porous support structure (36) which carries the fuel cells (22) on its two parallel surfaces. A plurality of passages (38) are defined between the porous support structure (36) and the first distribution member (28) which distribute and remove the first reactant from the anodes (40). Each second module (26) comprises a second distribution member (54) formed from two corrugated ceramic plates (58,60) which define internal passages (56) for the supply of a second reactant to the fuel cells (22). A plurality of passages (62) are defined between the fuel cells (22) and the second distribution member (54) which distribute and remove the second reactant from the cathodes (44).
