氢电极

The catalytic properties of the Pd/p-Si electrode for hydrogen evolution under illumination and in darkness were studied with the constant current polarization method.

重点研究了Pd/p-Si电极在光照前后的催化析氢性能。

The industrial method for making hydrogen are:(1) Water electrolysis, with nickel plating 15% of the iron electrode electrolytic potassium hydroxide solution;(2) from natural gas or liquefied petroleum gas system for hydrogen cracking;(3) water gas law, namely the system of hydrogen from coke or anthracite.

氢气的工业制法主要有：（1）水的电解，用镀镍铁电极电解15％的氢氧化钾水溶液；（2）从天然气或裂解石油气制氢气；（3）水煤气法，即从焦煤或白煤制氢气。

The phase structure,hydrogen storage performance and electrochemical performance of the alloys were studied by XRD and three-electrode test system.

采用X射线衍射和三电极测试体系研究了合金的相结构、贮氢性能和电化学性能。

Draw a conclusion, a better parameters was found in fabrication of polycrystalline silicon thin film on glass at middle temperature: amorphous silicon film to be annealed were deposited at a certain temperature on glass substrate and fused quartz by plasma enhanced chemical vapor deposition method, using SiH_4, H_2 mixture.
