The routes for methanol reforming to hydrogen and the types of catalysts for methanol steam reforming(MSR)are described.The workflow of vehicle-mounted MSR hydrogen production-power generation system and the importance of micro reactor for the system are briefly described.Research status on the relating reactors is introduced,including membrane reactor,cylindrical micro reactor,plate micro reactor and five kinds of porous micro-channel catalyst carriers.Development trend of vehicle-mounted MSR hydrogen production technology is also outlooked.It is shown that vehicle-mounted MSR technology represents the trend of hydrogen supply for hydrogen energy vehicles,and selective laser melting(SLM)additive manufacturing is the solution to realize the controllable micro channel structure of the carrier for the catalyst.Under satisfying the constraint conditions of the manufacturing feasibility of SLM,the relationship between the structural parameters of porous micro channel of the carrier and its hydrogen production performance is the main research direction.
