Electrohydrogenesis or biocatalyzed electrolysis is the name given to a process for generating
hydrogen gas from organic matter being
decomposed by bacteria. This process uses a modified
fuel cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requ ...
to contain the organic matter and water. A small amount, 0.2–0.8
V of electricity is used, the original article reports an overall energy efficiency of 288% can be achieved (this is computed relative to the amount of electricity used,
waste heat lowers the overall efficiency). This work was reported by Cheng and Logan.
