Abstract: An electrochemical analysis apparatus for developing a fuel cell catalyst is provided to compare quantified current densities of catalyst points in cyclic voltammetry(CV) and quickly derive composition ratio of individual metal in developing alloy catalysts. The apparatus is fabricated of: an automatic dispenser(15) that has optionally relative electrode(21) and reference electrode(22) or micro injector and is movable in X-Y-Z axis direction; a precursor chamber(16) that contains a metal precursor solution generated by dissolving different metal salts in a proper solvent; a combinatorial solution storage plate(17) that has multiple tubes containing a mixture solution which comprises the metal precursor solution with different compositions and contents; a reactive electrode array(18) having multiple catalyst points based on multi-component alloy, which are formed by dispensing the mixture solution to the conductive plate; a microfine hole plate(19) having multiple thru-path holes corresponding to the catalyst points; and a potential measuring device(23) electrically connected to the array as well as the relative electrode and the reference electrode, simultaneously.
