Our newspaper Tokyo the compound semiconductor that put in order of system of accrete of university of island of electric Japan blessing will be versed in associate professor of course assist cane passes the indium that make, gallium and arsenic element mix into to enter carbon on November 2 velar experiment, development goes the principle that uses compound semiconductor low cost to make tall purity hydrogen. New method reduces cost 10%% left and right sides about than the method of hydrogen of vanadium alloy moulding that uses at present.

At first, zun Teng's research is hydrogen of the eliminate in the compound semiconductor that how uses in high speed communication, change idea begins to study hydrogenous precision makes a technology later. He made the P that joins carbon in the indium on aluminous substrate, gallium and arsenic semiconductor semiconductor in the experiment film, discover compound of this kind of semiconductor film can filter as hydrogen medium filters hydrogen. In using pressure difference to undertake hydrogen passes through an experiment, hydrogen forms pH indicator of a proton to pass film, and impure content was not passed through, make went out almost the hydrogen of 100%% purity. He expresses, will continue to be opposite henceforth the semiconductor that does not use toxic element undertakes experiment and hydrogen pass through speed test and verify.

Hydrogen is regarded as clean the sources of energy, the hydrogen of tall purity is used extensively at the domain such as careful chemical, semiconductor and fuel cell. But the methodological purity that extracts hydrogen from inside the sources of energy such as coal, natural gas normally is insufficient, and make the model of alloy of precious metal vanadium that tall purity hydrogen uses normally hold high through law cost.
