Liquid thermosetting sealing agent for polymer electrode membrane fuel cell, single cell formed with sealing agent, its process, and process for regenerating polymer electrode membrane fuel cell

摘要

A liquid thermosetting sealing agent for a polymer electrode membrane fuel cell having separators and a membrane electrode assembly laminated, whose the viscosity at the application is from 1,000 to 9,000 Pa.S, can be used to prepare a highly durable seal for a polymer electrode membrane fuel cell, to produce a single cell having a highly durable seal and to recover the fuel cell whose seal becomes abnormality.
