Membrane Electrode Assembly (MEA)

The core component of a fuel cell where electrochemical reactions occur, containing catalysts like platinum.

Tungsten oxide (WO3) coating

A protective coating applied to fuel cell electrodes that exploits metal-insulator transition properties to selectively conduct electricity based on proton intercalation/deintercalation.

Metal-insulator transition (MIT)

A phenomenon where an insulator develops electrical conductivity when exposed to external factors such as changes in ambient gas concentration or temperature.
