Molten carbonate electrolyte creepage barrier
This patent describes a fuel cell electrical power generation apparatus comprising: fuel cell means including an anode, a cathode and an electrolyte matrix containing a quantity of a molten carbonate electrolyte between the anode and the cathode: and creepage barrier means for substantially preventing electrolyte creepage at the anode of the fuel cell stack. The creepage barrier means comprises at least one relatively thin layer of predetermined material which is poorly wet by the electrolyte. The thin layer is disposed in a predetermined position intermediate an outermost anode end of the fuel cell and facing outermost end of the electrolyte matrix in such a way as to substantially prevent electrolyte creepage at the anode end of the fuel cell means.
