To extend the range of biofuel cell applications, we wish to increase their maximum operational temperatures. Using a thermostable alcohol dehydrogenase as a biocatalyst, we prepared an enzyme‐immobilized bioanode that can operate at high temperatures. The catalytic current for ethanol oxidation was increased using this electrode at temperatures up to 80 °C.
