PGM-free cathode catalyst

Cathode catalyst formulations that avoid platinum-group metals, cutting the historically dominant materials-cost barrier to scaling microbial fuel cell reactors.

Where it's used

Microbial fuel cells & bioelectrochemical systems
Electrogenic bacteria oxidize organic matter at an anode and hand off electrons to an external circuit, turning wastewater, soil or plant root exudate directly into low-grade DC electricity — a technology direction opposite to microbial electrosynthesis, generating power from waste rather than consuming it to make chemicals.
