A fuel cell is provided to include a cell stack in which unit cells are stacked in a first direction, an end plate disposed at the end of the cell stack, and a current-collecting plate disposed between the end plate and the end of the cell stack. The current-collecting plate includes a conductive area having a conductive surface, which is in electrically conductive surface contact with a reaction surface of the end of the cell stack, and configured to collect power generated by the cell stack, and an airtight area having an airtight surface, which is in airtight surface contact with a non-reaction surface of the end of the cell stack, and surrounding the conductive area. The degree to which the conductive surface protrudes toward the end of the cell stack is different from the degree to which the airtight surface protrudes toward the end of the cell stack.
