To provide a manufacturing method of a fuel cell in which a reaction layer can be formed efficiently and safely for a worker engaged in work.
This manufacturing method is for the fuel cell which comprises a first substrate formed with a first gas passage, a first current collector layer formed on the first substrate, a first gas diffusion layer formed on the first current collector layer, a first reaction layer formed on the first gas diffusion layer, an electrolyte membrane formed on the first reaction layer, a second reaction layer formed on the electrolyte membrane, a second gas diffusion layer formed on the second reaction layer, a second current collector layer formed on the second gas diffusion layer, and a second substrate formed with a second gas passage. At least one of the first reaction layer and second reaction layer is formed by coating a reaction layer forming a material on the substrate formed with the gas passage and the gas diffusion layer while making an inert gas flow in the gas passage.
