Fest-Elektrolyt-Brennstoffzellenstapel.

摘要

A fuel cell has a plurality of first and second plate members (9,10) laid one on another with a predetermined phase relationship therebetween. Each first plate member (9) houses a cell (6). The first plate member (9) includes a cell-housing portion (11a), a cell-insertion opening (11) having two spaces (11b,11c) communicating with opposed openings of an inner-cell flow passage (f1) of the housed cell and a plurality of communication openings (12,13). The second plate member (10) includes an inter-cell flow passage forming portion facing (14a) the cell housed in the first plate member, an inter-cell flow passage forming opening (14) having two spaces (14b,14c) and a plurality of a plurality of communication openings (15,16). The inter-cell flow passage forming portion forms an inter-cell flow passage (f2) between adjacently disposed cells as the first and second plate members are laid one on the other. The communication openings and the spaces of the plate members provide reactant feed passages and reactant exhaust passages for the inter-cell flow passage and the inner-cell flow passage.
