TL;DR: Fuel cells vary greatly in their power output, ranging from large-scale building-integrated systems, known as “combined heat and power” systems, to those that provide just enough power to operate electronics in special circumstances, such as an implanted device for sensing and controlling glucose levels in the body.

TL;DR: X-ray absorption spectroscopy shows that reaction with oxygen results in destruction of the [4Fe-4S] domain of the active site H-cluster while leaving the di-iron domain (2FeH) essentially intact, suggesting that a very high level of discrimination can be achieved by subtle factors such as electronic effects (specific orbital overlap requirements) and steric constraints at theactive site.

TL;DR: This tutorial review describes studies of hydrogen production and oxidation by biological catalysts--metalloenzymes known as hydrogenases--attached to electrodes using specialised electrochemical techniques to allow assessments of catalytic rates and performance under different conditions, including the presence of O2, CO and H2S.

TL;DR: It is established that the membrane-bound hydrogenase from the beta-proteobacterium Ralstonia eutropha H16, when adsorbed at a graphite electrode, exhibits rapid electrocatalytic oxidation of hydrogen that is completely unaffected by carbon monoxide and is inhibited only partially by oxygen.
