Catalytic bioethanol hydrogen production is expected to be an effective way to replace fossil fuels with clean and renewable energy, and has drawn wide attention in recent years. This paper introduces the research status of hydrogen production and the related applications of fuel cells, summarizes the advantages of hydrogen production from bioethanol and the reaction process. The catalytic effects of rare earth metals represented by Ce and La in the hydrogen production of ethanol are reviewed in detail, and the water vapor shift reaction, water vapor shift reaction, CO selective oxidation reaction and black carbon oxidation The reaction of rare earth metals was discussed. On the basis of reviewing the related research progress, it provides suggestions for the development of bio-ethanol hydrogen catalyst.
