Abstract: An electricity supply device includes two conductive substrates, a chemical-electrical conversion module and a sealing structure. The chemical-electrical conversion module is disposed between the conductive substrates, and includes two diffusion units and a membrane electrode unit. One diffusion unit is disposed adjacent to one conductive substrate while the other diffusion unit is disposed adjacent to the other conductive substrate. The membrane electrode unit is disposed between the two diffusion units. The sealing structure includes a first protruding structure and a second protruding structure. One end of the first protruding structure is against to one conductive substrate. One end of the diffusion unit and one end of the membrane electrode unit are against to the inner side of one end of the first protruding structure. The second protruding structure is disposed next to the first protruding structure.

Abstract: A fuel cell voltage measurement device includes a main beam provided at two sides with a transverse slot each for slidably receiving a plurality of slides therein, and a plurality of retractable probe assemblies separately mounted on the slides to move along with the slides. Therefore, the retractable probe assemblies are applicable to contact with fuel cell bipolar plates having different heights and/or thicknesses, making the voltage measurement device highly practical for use. A voltage signal collecting unit is provided on a top of the main beam for directly collecting the measured voltage signals to obtain a voltage state of the fuel cell.
