Abstract: An embodiment fuel cell including a high temperature polymer electrolyte membrane includes an electrolyte membrane including a phosphoric acid-doped polymer of intrinsic microporosity, a cathode disposed on a first surface of the electrolyte membrane, and an anode disposed on a second surface of the electrolyte membrane, the second surface opposite the first surface.

Abstract: A high-temperature polymer electrolyte membrane fuel cell including a polymer of intrinsic microporosity that prevents phosphoric acid poisoning and a method for manufacturing the same are disclosed. It is possible to improve the electrochemical efficiency of high-temperature polymer electrolyte membrane fuel cells based on development of a polymer of intrinsic microporosity with thermal stability and cationic conductivity.

Abstract: Disclosed are an ionic conductivity measurement device and method for a fuel cell, which enable accurate measurement of ionic conductivity of a membrane electrode assembly for a fuel cell under various conditions. The ionic conductivity measurement device includes a main body frame, a clamp handle mounted to the upper portion of the main body frame, a lift shaft connected to the clamp handle so as to be movable upwards and downwards, a motion jig mounted to the main body frame so as to be movable upwards and downwards and including an upper support frame connected to the lower end of the lift shaft and a specimen support frame connected to the upper support frame, a lower support frame mounted to the lower end portion of the main body frame, an upper probe pin mounted to the upper support frame, and a lower probe pin mounted to the lower support frame.
