Enzymes power up : The limiting performance characteristics of hydrogenases in bioelectrocatalysis was studied. A comparison of bioelectrocatalysis with catalysis by noble metals such as Pt, as used in low‐temperature H 2 –O 2 fuel cells, shows that hydrogenase electrodes are similarly active in the consumption of dissolved H 2 as are Pt‐based fuel electrodes.
