[0002] Methanol is an organic compound containing carbon and hydrogen that is liquid at room temperature and pressure, making it easier to store, transport, and use. The methanol-to-hydrogen power generation process primarily involves two steps: catalytic reforming of methanol and fuel cell power generation. During the catalytic reforming process, methanol reacts with water under specific conditions to produce hydrogen. The resulting hydrogen is then fed into the fuel cell stack, where it generates electricity through an electrochemical reaction. This technology, known as methanol reforming hydrogen fuel cell technology, allows for immediate production and immediate use, reducing concerns about hydrogen transportation, storage, and safety, while also lowering the cost of hydrogen.
