The present invention relates to: a fuel cell which includes a stack part (21) formed by stacking a membrane electrode assembly and a separator, and in which the membrane electrode assembly and the separator each include a communication passage part to form a communication passage for allowing fuel gas or oxidant gas to flow, the communication passage formed by the communication passage parts is opened at a positive end portion and a negative end portion of the stack part (21), and one end of the communication passage is sealable; and a method and an apparatus for assembling the fuel cell. The fuel cell has a problem of not being easy to manufacture, for example. This is because positive and negative polarities of the fuel cell are determined when the stack is assembled; to dispose stacks having the same configuration with their polarities inverted, the stack whose polarities are inverted and the stack whose polarities are not inverted need to be assembled individually. The present invention has been made to solve the problem by forming the positive and negative end portions of the stack part (21) in the same shape, for example.
