The hydrogen oxidation kinetics of Cu and Pt point contact-electrodes on proton conducting BaZr0.7Ce0.2Y0.1O3-delta (BZCY72) were studied over a range of temperatures and hydrogen pressures using impedance spectroscopy. Characteristic capacitances were used to identify process contributions as charge and mass transfer, then Langmuir adsorption theory and Butler-Volmer charge transfer formalism were used to propose a hydrogen oxidation model to describe the experimental data. The charge transfer hydrogen pressure dependencies were pH(2)(3/4) for Cu, attributed to a high occupancy of adsorbed oxygen at three-phase boundary sites in the water-vapor containing atmosphere, and pH(2)(-1/4) for Pt, corresponding to a hydrogen saturated interface. The Cu and Pt point contact electrodes exhibit similar temperature dependencies for charge transfer, with activation enthalpies of 0.82 and 0.93 eV, and pre-exponentials of approximately 160 and 1000 Omega(-1)cm(-1), respectively. Mass transfer dominated the total polarization resistance of both metal point contact electrodes, exhibiting a pH(2)(1/2) hydrogen pressure dependency. The activation enthalpies are 1.21 eV for Cu and 0.73 eV for Pt, reflecting the higher catalytic activity generally expected for Pt. Preexponentials for mass transfer of approximately 10,000 Omega(-1)cm(-1) for Cu and 2.6 Omega(-1)cm(-1) for Pt, indicate that Cu utilizes a much larger active interface. Cu may be a suitable candidate electrode material for use in carbonaceous atmospheres, but the results of this work indicates that it suffers from a high activation enthalpy for mass transfer in the hydrogen oxidation reaction.
