WebThe water in the fuel cell is oxidized to a hydroxy radical via the following reaction: H 2 O → OH• + H + + e −. The hydroxy radical then oxidizes carbon monoxide to produce carbon dioxide, which is released from the surface as a gas: CO + OH• → CO 2 + H + + e −. [16] Using these OH groups in the half reactions, they are also expressed as: WebWhat is a hydrogen fuel cell and how does it work?
