Title:
MANUFACTURING METHOD OF GAS DIFFUSION LAYER FOR SOLID POLYMER FUEL CELL AND SOLID POLYMER FUEL CELL
Document Type and Number:
Japanese Patent JP2006004735
Kind Code:
A
Abstract:
To reduce damage of a polymer electrolyte membrane caused by projections of fibers of a gas diffusion substrate.
A manufacturing method of a gas diffusion layer contains a process where a polymer thin membrane 2 is arranged on a gas diffusion substrate 1, they are heated at a melting temperature or higher of the polymer thin membrane 2, and at the same time, the polymer thin membrane 2 and the gas diffusion substrate 1 are pressed to form the gas diffusion layer 7.
