Enzymatic fuel cell

Enzymatic fuel cells using biological redox molecules now enable moderate-temperature power without harsh, corrosive chemicals.

What it is

The technology uses enzymes to catalyze biological redox reactions between fuel and oxidant, generating an electrical current inside a fuel-cell structure. It targets moderate operating temperatures rather than high-heat operation typical of conventional fuel cells, reducing corrosion risk at the cell components. What used to require licensing and proprietary enzyme-cell designs can now be built by anyone using the disclosed chemistry and architecture.

What you could build

Launch portable off-grid devices and indoor micro-power systems using enzyme-based enzymatic fuel cells with moderate-temperature operation.
