Abstract: A direct type fuel cell power generator comprises an anode electrode including an anode catalyst layer, a cathode electrode including a cathode catalyst layer, a fuel container comprising at least two electromotive portion units, each of which comprises an electrolyte film disposed between the anode electrode and the cathode electrode, the fuel container housing a fuel therein, and a fuel flow path to supply a fuel in the electromotive portion unit. In the power generator, the fuel flow path has a flow path which produces flow-back again from the fuel container to the first electromotive portion unit via the first electromotive portion unit and the second electromotive portion unit, and which is not branched during the flow-back.

Abstract: The invention is capable of suppressing drop of power in power generation for a long period of time, and suppressing discharge of harmful substances.

Abstract: The invention provides a method for inspecting a fuel cell that can simply inspect fuel cell characteristics.

Abstract: Disclosed is a fuel cell comprising a fuel cell body (stacked body) including a unit cell having an electromotive section in which an electrolyte membrane is sandwiched between a fuel electrode and an oxidant electrode, and a liquid fuel tank for storing a liquid fuel that is to be supplied to the fuel cell body and connected to the fuel cell body. The liquid fuel is introduced by the capillary action into the unit cell included in the fuel cell body and vaporized within the unit cell so as to be supplied to the fuel electrode, thereby generating an electric power. The liquid fuel tank is provided with a pressure adjusting mechanism for introducing a required amount of the liquid fuel from a liquid outlet port into the unit cell.
