The system comprises a water tank (1), a fuel storage tank (2), a fuel water proportioning pump (3), a mixer A (4), a fuel atomizer (5), a second heat exchanger (26), a first heat exchanger (25), dehydration tanks (27, 28 and 12), a carbon monoxide removal reactor (11), a catalytic combustion reactor (6), a fuel water reforming reactor (29), a composite air-cooling heat sink (22), a hydrogen-air pressure balancer (14), a fuel cell cooling liquid tank (13), a compressed air heat exchanger (23), a fuel cell cooling circulation pump (15), a recycled hydrogen compressor (21), a hydrogen-rich storage tank (19), a hydrogen recycle membrane separator (17), a hydrogen fuel cell pack (16), an exhaust purifier (7), an expansion compressor (9), a control valve (18), a (normal-pressure fuel water) vapor-liquid separator (20), a mixer B (8), a mixer C (10), a mixer D (24), a steam trap (30), a system controller (31), a one-way valve (41) and valves (42-54). By applying an energy state theory, a vapor-liquid two-phase coexistence constant-temperature condensation or evaporation principle and phase-change heat-transfer highest efficiency principle, hydrogen production by reforming and constant-temperature control on a hydrogen fuel battery are achieved.

Description

technical field [0001] The invention relates to the fields of new energy power generation, renewable energy power generation, clean energy power generation, hydrogen fuel cell power generation and the like. In particular, hydrogen fuel cell vehicles have been developed for many years and have not been widely used. There are two bottlenecks: one is that the storage and transportation of hydrogen sources has always made hydrogen uneconomical; the other is the price of hydrogen fuel cells. The high cost and short lifespan make it difficult to commercialize hydrogen fuel cells. Although many researchers have used reforming technology to reform liquid fuel and water to produce hydrogen to achieve distributed or mobile hydrogen production, the stability of the reforming hydrogen production system has not been well resolved. Reforming hydrogen generation technology has not been commercialized. According to the theory of energy states, the use of liquid fuel and water reforming to p...

Even if pure electric vehicles solve the battery mileage problem, the future charging demand will still have the problem of fossil electricity pollution transfer

[0003] In recent years, hydrogen production technology using liquid fuel and water reforming has become the key breakthrough direction of new energy technology research. According to the research on energy state, the hydrogen produced by the reforming of an equal volume of methanol with water is twice that of an equal volume of liquid hydrogen. Methanology defines methanol as a liquid hydrogen storage material, which has been recognized by the public, and sufficient attention and investment have been paid to the research on hydrogen production technology of alcohols (methanol or ethanol) in the world, but many studies have failed to form commercialization
