A hybrid enzymatic zinc-air fuel cell

A hybrid enzymatic zinc-air fuel cell

A hybrid biofuel cell, a zinc-air cell employing laccase as the oxygen reduction catalyst is investigated. A simple cell design is employed; a membraneless single chamber and a freely suspended laccase in the buffer electrolyte. The cell is characterised based on its open-circuit voltage, power...
