This invention provides a process for producing a separator for a fuel cell which can separate a gas present between adjacent cells for a fuel cell. In producing a separator for a fuel cell using a metallic material such as titanium, a conductor having a high level of electrical conductivity is generally formed on the surface of the separator to reduce contact resistance between the separator and a gas diffusing layer and the like.

An exhaust manifold includes an open/close valve that switches between either closing or opening the exhaust path of a collection section, and switches the exhaust path of the exhaust gas between passing through or not passing through a bypass path containing an upstream catalyst. There is a partition wall structure in a pipe-mounting member so that when the valve is closed such that the exhaust gas during cold start is led to the upstream catalyst, the exhaust paths for each of the branch pipes on the upstream side of the valve inside a collection section are independent from one another. When the valve is closed, the downstream side of each of the branch pipes is not continuous inside the collection section, so the flow of air is prevented in this section, and exhaust interference and loss of exhaust heat are reduced.
