PURPOSE:To increase corrosion resistance of a manifold to supply a steady gas to fuel cell by mounting a protection cover made of fluorine resin in the inside of a manifold. CONSTITUTION:A PFA sheet 7 is formed so as to be mounted in the inner surface of a manifold 8, then mounted in the inside of the manifold 8. since the PFA sheet 7 is bonded in several portions to the manifold 8, it hardly comes out from the manifold 8. The PFA sheet 7 is formed by melting once, pinholes are very few compared with a coating film, and practically no pinhol film can be formed. Therefore, direct contact of fuel gas and oxidizing agent gas of a fuel cell with manifold material is surely prevented. Corrosion resistance of the manifold 8 can be increased and a steady gas is supplied to the fuel cell. |
