Abstract: Provided is an assembly method using an assembly tool used when a component is assembled to each of a plurality of connection ports to provided at an upper surface of a fuel-cell stack and communicating with a plurality of communication holes. The assembly tool includes a base portion positioned on the upper surface of the fuel-cell stack and a plurality of covering portions covering the plurality of connection ports. Each of the plurality of covering portions is, relative to the base portion, provided movably between a covering position for covering a corresponding one of the connection ports and a non-covering position accessible to a corresponding one of the connection ports.

Abstract: A method and apparatus for manufacturing a membrane electrode assembly are provided, which can efficiently peel an electrode layer from a base material. A manufacturing apparatus for manufacturing a membrane electrode assembly of a fuel cell including a pair of electrode layers and an electrolyte membrane, the apparatus including: a transport device which transports the base material on which one cathode electrode layer of the pair of electrode layers is formed and which is connected to a transport sheet via an adhesive layer together with the transport sheet; a transfer device which transfers the one cathode electrode layer to the electrolyte membrane; a peeling device which peels the cathode electrode layer from the base material; and a cooling device having a spraying device which is directed to a start point portion for the peeling and sprays a cooling gas.

Abstract: A manufacturing apparatus for a fuel cell stack includes a pressing unit, an overall load detection unit, and an electrode load detection unit. The pressing unit presses the entirety of a stack body containing multiple power generation cells stacked together, along a stacking direction. The overall load detection unit detects an overall load acting on the entire stack body including a seal stack portion in which seal members are stacked and an electrode stack portion in which electrodes are stacked when the stack body is pressed by the pressing unit. The electrode load detection unit detects an electrode load acting on the electrode stack portion when the stack body is pressed by the pressing unit.

Abstract: In a method of activating a fuel cell, after a voltage application step is performed, a humidifying step is performed. In the voltage application step, a hydrogen gas is supplied to an anode, and an inert gas is supplied to a cathode. In the meanwhile, cyclic voltage which is increased and decreased within a predetermined range is applied to the fuel cell. In the humidifying step, in a state where application of the voltage is stopped, a humidified gas containing water vapor is supplied to at least one of the anode and the cathode.
