Summary for Patent: 5,549,982
Title: Fuel cell
Abstract:In a fuel cell, a plurality of cells juxtaposed side by side to constitute together a cell layer and a plurality of cell layers thus prepared are stacked one above another to constitute together a multi-layered fuel cell assembly, In each cell layer, adjacent cells are interconnected and supported via a cell connecting plate member. This connecting plate member includes a cutout extending from one edge to the other opposite edge of the member along the entire length thereof for allowing insertion of opposed opened sides of the adjacent cells to which the inner cell flow passages are opened. The cutout has a depth substantially same as the thickness of the cell. An abutment face is defined in each end face of a pair of partition wall portions adjacent the cutout and a corresponding abutment face is defined in each closed side of the cell adjacent the opened side. As the cutout is partitioned by the opposed partition wall portions of the cutout and by a further adjacent cell connecting plate member, there is formed a connecting flow passage which interconnects the inner cell passages of the adjacent cells of the layer and which is partitioned from an inter-cell flow passage formed between the cells adjacently stacked in the assembly.
