THERMO-HARDENING TYPE LIQUID SEALING COMPOUND FOR SOLID HIGH-POLYMER TYPE FUEL CELL, UNIT CELL WITH SEAL FORMED OUT OF THE SEALING COMPOUND AND MANUFACTURING METHOD FOR UNIT CELL, AND SOLID HIGH-POLYMER TYPE FUEL CELL AND ITS GENERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a liquid sealing compound capable of form a uniform seal at a comparatively low temperature and equipping the produced seal with a long sustaining durability under the fuel cell atmosphere. SOLUTION: The liquid sealing compound q1 of thermo-hardening type for solid high-polymer type fuel cell formed out of laminating separators 1 and 2 and a power-generating element MEA has a viscosity of 1000-9000 Pa.s when it is applied. This is applied at an applying speed in the range set previously in accordance with the sealing compound viscosity, application pressure, and the width and height of the seal to be produced and left hardening in the temperature range 120 deg.C5 deg.C and for the preset processing time so that the intended seal is formed.
