POLYMER SOLID-ELECTROLYTE FUEL CELL - SUTONHARUTO ASSOC INC

Title:

POLYMER SOLID-ELECTROLYTE FUEL CELL

Document Type and Number:

Japanese Patent JPH0644982

Kind Code:

A

Abstract:

PURPOSE: To provide a fuel cell in which sufficient current density can be extracted even by an indirect humidification method at normal pressure, and electrode characteristics can be utilized to the full. CONSTITUTION: The film thickness of a solid polymer diaphragm is set to be 5 to 70μm in a high molecular solid electrolyte fuel cell. The maximum limit current density is obtained in this range, a wet state in which no deterioration of electrode characteristics can be maintained even by indirect humidification. The diaphragm is made of high molecules, and by volatilizing the solvent of solid polymer dispersion solution, thin film thickness can easily be formed.
