Abstract
A humidifier for a fuel cell includes a humidifying unit that produces humidified air. The humidifying unit includes: a first separator having dry gas channels; a second separator having water-containing gas channels; a humidifying membrane that provides moisture contained in gas flowing through the water-containing gas channels to dry air flowing through the dry gas channels to produce the humidified air; protective films that reinforce the humidifying membrane; and a sealing material that is provided along a first outer edge portion of the humidifying membrane with the humidifying membrane and the protective films stacked together, and that seals between the dry gas channels and the water-containing gas channels. The humidifying membrane has a close contact region between the first outer edge portion of the humidifying membrane and a second outer edge portion of the protective film.
