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...

Problems solved by technology

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

Mercedes-Benz successfully researched methanol reforming hydrogen production and hydrogen fuel cell electric vehicles for a long time ago, but finally gave up the commercialization process. The reason is that reforming hydrogen production is a chemical process, and it is difficult to control the stability of the process. car use

The key reason why countries have not been able to break through the commercialization of liquid fuel water mobile and distributed reforming hydrogen production technology is not safety issues, cost issues and reliability issues, but stable operation issues

Moreover, for hydrogen fuel cell technology, in addition to the hydrogen source, it also involves an oxygen source. If the oxygen source uses air at atmospheric pressure, the life of the hydrogen fuel cell is affected by the quality of the ambient air. Compressed air internal friction constraints
