Abstract
In a fuel cell structure having an assembly of an electrolyte layer and an electrode formed on the electrolyte layer, a gas separatoris laminated on the electrolyte layer and the electrode and forms, in combination with the electrode, a gas flow path to make a flow of a reactive gas that is subjected to an electrochemical reaction. A first water guide element is provided between the electrode and the gas separatorand is arranged to enable migration of water from and to the electrode and to continuously guide water in an electrode plane direction. A gas outletis open at one end of the gas flow path to be at least partly overlapped with one end of the first water guide element and discharges the flow of the reactive gas from the gas flow path. The gas outletis designed to have a higher flow resistance of the reactive gas than a flow resistance in the gas flow path. This arrangement effectively improves the water discharge efficiency from the gas flow path formed in the fuel cell structure.
