FUEL CELL, AND METHOD AND APPARATUS FOR ASSEMBLING FUEL CELL

摘要

The invention relates to a fuel battery which comprises a stack unit (21) structured by stacking a membrane-electrode assembly and a separator and in which the membrane-electrode assembly and the separator have a communicatio n passage portion constituting a communication passage for communication of a fuel gas or an oxidizer gas, the communication passage constituted by the communication passage portion is open at the ends of both electrodes of the stack unit (21), and one end of the communication passage is closable. A fue l battery assembling method and an assembling device are also provided. Sinc e the positive electrode and the negative electrode of a stack of the above fuel battery are determined when the stack is assembled, when the polarities of the stacks having the same structure are inverted and arrayed, the stack s whose polarities are inverted and the stacks whose polarities are not inve rted need to be assembled separately, thereby conventionally causing a probl em that the manufacturing is not easy. According to the invention, the probl em is solved by a technique of fabricating both electrodes of the stack unit (21) whose ends have the same shape.
