For these processes, efficiencies above 50 % can be expected and could possibly lead to a major decrease of hydrogenproduction costs. The main technical issues for these high-temperature processes relate to materials development for corrosion resistance at high temperatures, high-temperature
membrane and separation processes, heat exchangers, and heat storage media. Design aspects and safety ar

Hydrogen is one of well-known clean energy source.
Several technologies are already available in the marketplace for the industrial production of hydrogen.
Hydrogen can be produced from a variety of feedstocks.

cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.
Fuelcells are direct energy conversion into electricity. So High electric conversion efficiency and carbon dioxide reduction is excellent.
Since 1999, A joint research for 2 years
after all, Succeed in first development
A small fuelcell, hydrogen tank, control equi
