    摘要： A fluid channel structure for polar plate of fuel cell includes a plurality of parallel passages provided in a reaction area of a polar plate, two through holes of fluid inlet and outlet provided on the polar plate, a plurality of communicating channels connecting the through holes to two ends of the passages, and a plurality of tunnels formed between the communicating channels and each of the through holes. The tunnels are formed by closing a top cover onto a locating zone formed on the polar plate near the through hole, so that slots formed at a lower side of the top cover are aligned with horizontal groove sections and vertical step sections formed in the locating zone to form the tunnels. The top cover bears a relatively large fluid pressure, enabling the fluid channel structure to transfer sufficient reactant fluid to the polar plate without the risk of leaking.

    摘要： A method for manufacturing membrane electrode assembly of fuel cell includes positioning an ion exchange membrane that is cleaned and trimmed to a predetermined size in advance to a base plate, mounting the base plate to a printing platform, attaching a printing plate to the platform, coating a catalyst solution on the printing plate with a scraper, printing the catalyst solution onto the ion exchange membrane with the scraper, heating the ion exchange with a heating board to a temperature of 70-80° C., and waiting for the ion exchange membrane to return flat to complete the coating of the catalyst solution on the ion exchange membrane. The printing and heating steps are repeated for both anode and cathode of the ion exchange membrane. The ion exchange membrane is further subject to hot pressing and then a piece of carbon cloth is positioned on the catalyst coating to serve as a diffusion layer. This completes the manufacturing of the membrane electrode assembly.
