    Abstract: 氫氣是乾淨且對環境友善的燃料,已被視為最具潛力的能源來源之一,在許多產氫方法中,其中又以結合再生能源的水電解是最具前景,且最簡單獲得高純度產氫的方法。

    ;Hydrogen is clean and environmentally friendly as a green fuel, and has been regarded as one of the most potential energy resources. Among
    the methods of hydrogen production combined with the renewable energy, water electrolysis is the most promising solution, and the simplest method to obtain high-purity hydrogen.
    First of all the study, graphene supported IrO2 catalyst (IrO2/RGO) is composite by hydrothermal method. XRD, TEM, EDS and Raman tests are conducted to synthesis catalyst characterization, which reveal that IrO2 nanoparticle is uniformly supported on RGO surface.
    Secondly, by changing thin film forming parameters, e.g., catalyst loading, spin coating speed, and rotation of working electrode, attempts and performs to find out the connections between thin film process and electrochemical measurement like LSV, EIS, etc.
    Experimental results show that with the more catalyst loading, the better electrolysis performs; and the loading of 70μL gives the best performance in water electrolysis. By increasing the spin coating rate, electrolysis get worse; and the spin coating of 250rpm yields the best performance. As to the rotation of working electrode, 2000rpm gives the best hydrogen production efficiency and the lowest concentration polarization.
