Research Abstract	Carbon materials such as high density graphite, glassy carbon composite, resin sintered graphite are going to apply for separater of Polymer Electrolyte Fuel Cell. But, bonding properties of these materials is very poor. Soft soldering (Sn-Pb) after Cu-Ag-Ti metalizing on carbon materials was studied in this research. Main results obtained are as follows. (1) Void free bonding joint is obtained at high density graphite and resin sintered graphite. But, Cu-Ag-Ti metalizing layer was peeled off at glassy carbon composite. (2) Joint strength (4 point bending strength) equivalent to bending strength of base graphite is obtained at above mentioned two graphites.
