PURPOSE:To obtain a thin type cell unit having high voltage by arranging junction bodies having a small area in the plane, and collecting current in series electrically. CONSTITUTION:Plural sheets of junction bodies are arranged and sandwiched in the plane between two sheets of insulating plates 11A and 11B so as to form a cell unit 10. The respective junction bodies 12 are formed by connecting gas diffusion electrodes 14A and 14B on both sides of a solid high polymer electrolyte film 13. When H2 and O2 are supplied to the junction bodies 12 by a raw material gas supply means, since cell reactions are generated respectively in the respective junction bodies, electric current is taken out from current collecting parts 21A and 21B by connecting H2 poles and O2 poles alternately in series. Under this constitution, a thin type cell unit capable of obtaining high voltage can be formed.
