PURPOSE:To make a device compact by providing a humidifier in a stack. CONSTITUTION:Hollow thread films 69 constituting oxygen gas supply piping 35 or hydrogen gas supply piping 45 are arranged in a cooling plate 51 arranged in a stack. In the hollow thread films 69, a film showing permeability to water is formed in a hollow thread shape, and the material is formed by bonding a support film to support a resin film to this porous resin film having a property of which water transmission speed is larger than gas transmission speed. In this constitution, humidification to oxygen gas and hydrogen gas supplied to respective cells can be performed in the stack by using an existing cooling water passage. |
