摘要:
Humidity adjusting films are sandwiched between the catalyst electrode layers and carbon fiber collector layers of a solid polymer type fuel cell. These humidity adjusting films are constructed from a conductive carbonaceous powder and a polytetrafluoroethylene. The moisture permeability as measured by the method stipulated in JIS L 1099 (B-1) is 1200 to 4000 g/m2 hr, and the mean thickness of the films is 5 to 100 μm.
