WebNov 25, 2024 · The production of hydrogen is often linked to its use to generate power using fuel cells which generally run on hydrogen, but any hydrogen-rich material can serve as a possible fuel source. However, this latter type of fuel is only really suitable for higher temperature fuel cells (650–900 °C) such as molten carbonate or solid oxide systems ... 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:
