摘要:
A fuel cell system that includes a cell unit comprising a fuel cell, a fuel tank unit for storing a fuel to be supplied to the cell unit, and a fuel feed unit for supplying the fuel from the fuel tank unit to the cell unit in a thin housing having a substantially rectangular parallelepiped shape. The fuel tank unit, the fuel feed unit, and the cell unit are located in a specific order in one direction between two opposite ends of the housing. The fuel tank unit includes a valve, which supplies fuel to the fuel feed unit and opens to supply the fuel to the fuel feed unit only when the fuel tank unit is mounted. The fuel feed unit connects sides of the fuel tank unit and the cell unit that face each other and reduces a pressure of a gaseous fuel supplied from the fuel tank unit.

A fuel cell system is provided which has a humidifying means (2) for directly humidifying a polymer electrolyte membrane (12) that serves as an ionic conductor. As the humidifying means (2), means is employed which has a water holding unit (21) comprised of a water-absorbing material and located in contact with the polymer electrolyte membrane to directly humidify the polymer electrolyte membrane (12) by utilizing a capillary action and further has a humidification water passage (28) comprised of a hydrophilic material and provided in the polymer electrolyte membrane so as to be connected to the water holding unit (21) to humidify the polymer electrolyte membrane (12) rapidly and uniformly. Such a constitution provides a fuel cell system that can directly humidify an ionic conductor.
