The invention discloses a method for preparing a fuel cell film pole, and a cathode catalyst layer is obtained by directly preparing non-noble metal catalyst. The method for preparing a film pole comprises the following steps: (1) preprocessing a proton exchange film; (2) after noble metal catalyst is made into slurry, coating the slurry on one side of the preprocessed proton exchange film to obtain an anode catalyst layer; (3) coating loaded transitional metal chelate on a cathode diffusing layer and hot processing the cathode diffusing layer by the protection of gases to directly obtain thecathode catalyst layer; and (4) plastically packaging in sequence of cathode diffusing layer-cathode catalyst layer-proton exchange film-anode catalyst layer-anode diffusing layer to obtain the fuel cell film pole. The invention can simultaneously prepare cathode catalyst and cathode catalyst layer, breaks through a traditional method for preparing the catalyst and then preparing the catalyst layer, greatly simplifies the preparation technology of the fuel cell film pole, reduces the preparation step, has simple operation and is convenient for mass production.
