Abstract
A first gas flow path is formed in a first substrate. The first substrate is processed in an ejection device to form a first collector layer, a first gas diffusion layer, a first reactive layer, and an electrolyte membrane. Similarly, the first substrate is processed to form a second reactive layer, a gas diffusion layer, and a second collector layer. A second substrate which has been processed to form a second gas flow path is then disposed on the first substrate to complete production of a fuel cell having a gas flow path formed therein the opening width of which is smaller than the particle diameter of the material constituting the gas diffusion layer.
