Abstract

Provided are conducting members for fuel cells obtained by applying a protective film forming agent to a surface-treated base material having a base material and at least one alloy plating layer formed on the base material in order to form a protective film on the alloy plating layer, and thereafter subjecting the surface-treated base material to an acid treatment. In the conducting members for fuel cells of the present invention, the protective film forming agent preferably contains a mixture of a compound having a thiol group and an azole-based compound, and/or an azole-based compound having a thiol group. In the conducting members for fuel cells of the present invention, the acid treatment is preferably a treatment using sulfuric acid or nitric acid.
