PURPOSE:To improve a cell life with a uniform catalyst layer formed using an electric reaction by adding an electric charge to a catalyst purposing to disperse the catalyzer in a spray vessel. CONSTITUTION:A catalyst is made to retain an electric charge by a nozzle 11 on the upper part of a spray vessel 12 purposing to improve a dispersion of the catalyst in the spray vessel 12. Therefore, since the electric charge is uniformly added to the catalyst to which the electric charge is sprayed and sprayed from the nozzle 11, the catalyzer sprayed from the spray nozzle 11 uniformly disperses in the spray vessel 12 as well as the catalyzer having the electric charge is repelling mutually and a spraying angle from the spray nozzle 11 expands. This enables the catalyst to be uniformly applied to a substrate 13 upper surface, an electrolyte layer provided to a catalyzer layer uniformed, a dispersion of a cell specific resistance eliminated, and thereby a life of a fuel cell improved. |
