A polymer ion exchange membrane for acidic electrolyte flow battery. The membrane is nitrogen heterocycles aromatic polymer, especially polybenzimidazole type polymer. A nitrogen heterocycles in the membrane interact with acid in the electrolyte to form donor-receptor proton transport network, so as to keep the proton transport performance of the membrane. The preparation condition for the membrane is mild, and the process is simplicity. The preparation method is suitable for mass production. The membrane is used in acidic electrolyte flow battery, especially in vanadium flow energy storage battery. The membrane has excellent mechanical stability and thermostability. In vanadium redox flow battery, the membrane has excellent proton conduct performance and excellent resistance to the permeation of vanadium ions.

Disclosed is use of a porous membrane and a composite membrane thereof in a redox flow batteries, and in particular the use thereof in a vanadium redox flow battery. The membrane can effectively realize the separation of ions with different valence states, and an ion transfer without any ion exchange group. The pore size and structure of the porous membrane can be controlled by filling an inorganic substance or grafting an ion exchange group in the pore, in order to improve the barrier properties of the porous membrane for vanadium ions and to increase proton conductivity.

A supported electrochemical catalyst used to produce a proton exchange membrane fuel cell, the supported anode catalyst including an electrically conductive support and Pt/Ni based alloy nanoparticles. The supported electrochemical catalyst can be synthesized using an improved microwave-irradiated polyol (IMIP) method, and a heat treating method while being subjected to a reduction reaction under an inert environment. The catalyst exhibits an improved carbon monoxide (CO) tolerance and high activity with respect to a hydrogen oxidation reaction. In addition, the manufacturing method for the supported electrochemical catalyst is simple, environmentally friendly, quick, and inexpensive.
