Synthesis and Oxygen Reduction Reaction Characteristics of Multi-Walled Carbon Nanotubes Supported PtxM(1-x)(M = Co, Cu, Ni) Alloy Catalysts for Polymer Electrolyte Membrane Fuel Cell

Improved durability of Pt/CNT catalysts by the low temperature self-catalyzed reduction for the PEM fuel cells

“…A 5 cm 2 unit cell (Fuel Cell Technologies Co.) was used to evaluate the cell performance with hydrogen and air as the reactant gases and detailed set-up and procedures are described in our previous work [28]. In the polarization test, the humidified reactant gases with 100% relative humidity were supplied to the anode and the cathode at ambient pressure with stoichiometric fuel to oxygen ratios of 1.5 and 2.0, respectively.…”
