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.

Ionic conductivity measurement device and method for fuel cell

A method of manufacturing a composite anode for a lithium ion battery and a composite anode for a lithium ion battery manufactured thereby. According to the method provide herein, since a metal catalyst precursor is reduced using Joule heating to obtain a carbon-metal catalyst composite layer, composite anode for a lithium ion battery having a large area in a short period of time can be provided, which is excellent in terms of economic feasibility. Further, since it is possible to manufacture a composite anode for a lithium ion battery with the improved lithium electrodeposition density and reversibility of lithium ions, a composite anode for a lithium ion battery having high capacity and improved life stability can be obtained.
