Method for manufacturing gas diffusion layer for fuel cell |
摘要 |
The invention is to provide a gas diffusion layer for fuel cells having excellent adaptability against load change by attaining a good balance between anti-dry-out properties and anti-flooding properties. The gas diffusion layer for fuel cells containing a substrate layer and an conductive fine particle layer is formed by coating a coating liquid for forming the conductive fine particle layer on at least one surface of a substrate for forming the substrate layer using a gravure roll and by a kiss coating. In coating of the coating liquid, a speed difference is generated between a line speed of transferring the substrate and a circumferential speed of the gravure roll, and apparent viscosity [eta(Pa·s)] of the coating liquid as determined by type B viscosimeter satisfies the following relations: 1.0<eta<200.0 (3 rpm) 0.2<eta<10.0 (30 rpm).
