PROBLEM TO BE SOLVED: To provide a fuel cell which is excellent in shape stability and airtightness and can be easily fabricated by constituting a separator of a layer containing a conductive carbon material on a base body surface by using metal containing a specific quantity of aluminium or titanium as a base body. SOLUTION: Since metal which is elastically deformable and plastically deformable and is excellent in tenacity and contains aluminium or titanium by 80wt.% or more, preferably, 90 to 98wt.% is used as a base body of a separator, the base body can endure mechanical impact since stress is relieved by elastic deformation or plastic deformation even when the stress is applied from the easily collapsing direction. Electric conductivity is imparted by a layer containing a conductive carbon material formed on a base body surface. Therefore, an inexpensive solid high polymer fuel cell having a separator easy to recycle can be obtained. |
