Gas diffusion cathodes with Ni alloy and Ni catalysts manufactured by chemical deposition were tested for H2production in a microbial electrolysis cell (MEC). In a continuous flow MEC, multi-component cathodes containing Ni, Mo, Cr, and Fe, at a total catalyst load of 1mgcm−2on carbon support demonstrated stable H2production at rates of 2.8–3.7LLR−1d−1with only 5% methane in the gas stream. Furthermore, a Ni-only gas diffusion cathode, with a Ni load of 0.6mgcm−2, demonstrated a H2production rate of 4.1LLR−1d−1. Overall, H2production was found to be proportional to the Ni load implying that inexpensive gas diffusion cathodes prepared by chemical deposition of Ni can be successfully used for continuous production of H2in a MEC.
