固体高分子型燃料電池の集電板の製造方法
Document Type and Number:
Japanese Patent JP4706673
Kind Code:
B2
Abstract:
To effectively remove generated water from an air electrode layer.
A current-collecting board opens on the side of the air electrode layer (oxidant electrode) 3 in communication with each other, and is formed of a foamed sintered metal having a plurality of foamed holes 6a of the capacity to aspirate water generated on the side of the air electrode layer 3 by capillary action. Penetrating in a direction to the air electrode layer 3, the foamed holes 6a open, and a plurality of through-holes 6b are formed so as to be supply routes of air (oxidant gas).
