A cell for a fuel cell comprises an electrolyte layer, a catalyst layer and a gas diffusion layer formed to be contacted to both sides of the electrolyte layer, an anode contacting hydrogen, and a cathode contacting oxygen and air, cations being transferred through the electrolyte layer or the operating temperature being equal to or less than 100° C., characterized in that the cell for the fuel cell has hollow portions hollowed up and down inside the gas diffusion layer. The manufacturing method uses a mold having the specific pattern to form the hollow portion in the gas diffusion layer using the micro needle or the micro lens so that the diffusion resistance inside the gas diffusion layer is lowered, making it possible to smoothly move fuel and reactants through the hollow portion and the reaction is smoothly performed even in a situation where fuel partial pressure is low. |
