GAS SEPARATOR FOR FUEL CELL AND FUEL CELL

摘要

A gas separator for a fuel cell has a first plate that forms one face; a second plate that forms the other face of the gas separator; and a third plate located between the first plate and the second plate. The third plate has a cooling medium flow path forming hole defining a cooling medium flow path between the first plate and the second plate and is provided in at least part of an area overlapping an electrolyte layer and electrode layers in lamination. A flow rate regulator is provided in the cooling medium flow path and regulates a flow rate to have a higher flow rate during power generation of the fuel cell. A temperature distribution is determined according to an operating condition of the fuel cell or an environment surrounding the fuel cell.
