Abstract
The present invention provides a catalytic layer-electrolytic membrane laminate for an unhumidified-type fuel cell, comprising an electrolytic membrane containing a strong acid; a conductive layer formed on one surface or both surfaces of the electrolytic membrane; and a catalytic layer formed on the conductive layer; wherein the conductive layer is formed of a fluorine-containing resin and carbon powder, and the conductive layer is thinner than the electrolytic membrane. The present invention provides a catalytic layer-electrolytic membrane laminate for an unhumidified-type fuel cell that can be practically used.
