Optimizing the power of enzyme-based membrane-less hydrogen fuel cells for hydrogen-rich H-2-air mixtures

Abstract:

The unusual ability of O2-tolerant hydrogenases (H 2ase) to produce electricity from a H2-air mixture (when used as the anodic electrocatalyst in a simple, membrane-less fuel cell) is investigated with the aim of establishing a strategy for raising volume power density, the measure of importance for miniature devices. Compacted mesoporous carbon electrodes provide a simple and inexpensive method for obtaining a large increase in productive enzyme loading, greatly increasing current densities ...
