Abstract
In an electrolyte membrane () for a solid polymer fuel cell, sealing ribs () of a predetermined height made of an electrolyte resin is formed integrally with the electrolyte membrane (). Using the electrolyte membrane, a membrane-electrode assembly () is formed, which is further processed into a fuel cell (). Thus, an electrolyte membrane and a membrane-electrode assembly which are capable of improving the sealing characteristic when incorporated into a fuel cell are obtained. Besides, a fuel cell improved in the sealing characteristic is obtained.
