摘要： A cell assembly is formed by stacking a first cell and a second cell. In the cell assembly, oxygen-containing gas flow passages are connected in series by an intermediate oxygen-containing gas flow passage, and fuel gas flow passages are connected in series by an intermediate fuel gas flow passage. An additional oxygen-containing gas is supplied to an oxygen-containing gas passage which includes the intermediate oxygen-containing gas flow passage. An additional fuel gas is supplied to a fuel gas passage which includes the intermediate fuel gas flow passage.

摘要： An intermediate plate is interposed between first and second sub-stacks. The intermediate plate has, defined in a surface thereof, an oxygen-containing gas mixing passage interconnecting an oxygen-containing gas outlet in the first sub-stack which is located upstream and an oxygen-containing gas inlet in the second sub-stack which is located downstream. In the first and second sub-stacks, an oxygen-containing gas is supplied from the oxygen-containing gas inlet and discharged to the oxygen-containing gas outlet at all times.

摘要： A fuel cell stack includes a plurality of unit cells each including a membrane electrode assembly and first and second metal separators sandwiching the membrane electrode assembly. The unit cells are stacked into a stack body, and the stack body is placed in a casing. Fluorocarbon resin sheets are provided between four sides of the stack body in parallel with the stacking direction of the stacked body and side plates of the casing, respectively. The fluorocarbon resin sheets fill gaps between stack body and inner surfaces of the casing.
