Abstract

A gas manifold for a fuel cell provided on the side of a fuel cell stack comprises a casing, a corrosion protection layer provided on contact areas between the casing and side of the fuel cell stack and portions adjacent thereto for protecting the casing from corrosion, an insulating layer provided on the outer surface of the corrosion protection layer for protecting the electrical insulation, and a thermal stress relief layer provided between the insulating layer and the corrosion protection layer for relieving the thermal stress therebetween. By the use of the gas manifold, electrical insulation between single fuel cells through the gas manifold and between the fuel cell stack and the gas manifold can be maintained for long periods of time, thus enabling the stable operation of the fuel cell for long periods of time.
