摘要： A fuel cell includes a membrane electrode assembly, and a first and second separators for sandwiching the membrane electrode assembly. The first separator has an oxygen-containing gas flow passage for allowing an oxygen-containing gas in a serpentine pattern to flow horizontally back and forth, and flow downwardly. Partition areas are provided along the oxygen-containing gas flow passage in the serpentine pattern. The partition areas are formed by partially cutting out a gas diffusion layer. Insulating seals for preventing leakage of the oxygen-containing gas are provided in the partition areas.

摘要： There is provided a fuel cell stacking body that allows a connector unit to be used even when the thickness of the fuel cells has been made thinner. A fuel cell stacking body is provided with stacked fuel cells that each have a membrane electrode assembly and separators that sandwich this membrane electrode assembly. The fuel cells generate electricity when fuel gas and oxidizer gas are supplied. The separators of the fuel cells are provided with terminals that enable voltage to be measured by being connected to connectors that are connected an external voltage measuring apparatus. One of the voltage measuring sections is formed at a different position, with respect to the stacking direction, from the voltage measuring section that is adjacent in the stacking direction. The spacing between terminals that are at the same position with respect to the stacking direction is kept at a distance that allows a connector unit formed by grouping together a plurality of connectors to be inserted.

摘要： A fuel cell of the invention has unified a processing circuit processing a cell voltage output signal of a fuel cell stack and a connector connecting an circuit unit with terminals provided extending from separators of the fuel cell, thereby having abolished connection points (in which harnesses are attached and detached) of an electrical circuit unit with the connector. So, for connection, reliability can be improved, and downsizing is possible. Moreover, with a casing enclosing the connector and electrical circuit unit, the fuel cell can be made compact and the processing circuit can be surely protected thanks to being shielded from surroundings, thereby handling as a unit being able to be facilitated.
