To form the solid oxide fuel cell (10), porous, compliant and conducting ano de and cathode buffers (22, 24) are disposed between the cell and anode and cathode flow fields (12, 14) respectively. Marginal gaps (30) between the anode and catho de flow fields and margins of the cell are formed in excess of the thickness of glas s based seal tape (32) disposed between the flow field margins and the cell margins. Upon compressing the flow fields and thus the buffer layers, the seal tapes are engaged by the flow fields and cell margins. Heat is applied to reach seal working temperatures to melt the glass-based seal which, upon cooling, solidifies or hardens to form hermetic seals along the fuel cell margins. |
