| description | PURPOSE:To provide an easily manufactured and stable diaphragm for a fuel cell by introducing a sulfonic acid group in a fluorine polymer sheet after specific mixed solution is applied on the fluorine polymer sheet and it is dried and heat treatment is carried out. CONSTITUTION:Mixed solution of carbon particles carrying electrode catalyst particulates and fluorine contained sulfonic acid polymer is applied on a fluorine polymer sheet, and it is dried and heat treatment is carried out within a specific temperature range. A sulfonic acid group is introduced in this polymer sheet, and a diaphragm for a fuel cell is obtained. In this diaphragm, electrode catalyst layers 27 are applied on both sides of an ion exchange membrane 26, and the carbon particles 28 carrying the electrode catalyst particulates 29 are contained in the electrode catalyst layers 27, and these are contacted partially with each other, so that mutual electric conductivity can be secured. Proper pores 31 exist between the carbon particles, and play a role as a flow hole of gas to the electrode catalyst layers. |
