Fuel cells have been highly considered as an alternative power source for the near future. The low temperature-operated proton exchange membrane fuel cells (PEFC) has gain interest for use in automotive and stationary applications. For Pt-metal alloy electrocatalysts, the cost to produce and commercialize fuel cells is high. Therefore, the major challenges in fuel cell research are to reduce the cost of the electrocatalyst either by lowering the Pt loading or by developing a non-noble catalyst. The exploration for new alternative Pt catalysts from such materials as a graphene-structure, coals has become the challenge in fuel cell research, although coals contained many impurities. The preparation of treated coals and their activity as an cathode catalyst for PEFC were investigated. The electrocatalytic activity for the oxygen reduction reaction over the catalysts was evaluated using a single-stack fuel cell and a rotating disk electrode.
