摘要： A sealed proton-exchange membrane fuel cell unit of this invention comprises an MEA component, a sealing unit, and current collectors for the positive and negative electrodes. The current collectors press the MEA components from each side. The MEA components comprise a proton-exchange membrane, a sealing unit, and the positive and negative electrodes attached to each side of the membrane. A sealing unit cover the edges of the proton-exchange membrane. First positioning units are located on each side of said sealing unit facing the respective current collectors of the negative and positive electrodes. At the corresponding locations on the current collectors of the negative and positive electrodes there are second positioning units. The first and second positioning units correspondingly match each other. First positioning units can be convex in shape on the surface of the sealing units. The second positioning units can be sealing grooves formed by cutting on the surface of the current collectors facing the MEA component. By matching the locations of the first and second positioning units, the negative and positive current collectors are not likely to slide against each other. Thus the cell is more tightly sealed, achieving better air-tightness.
