ABSTRACT:
A fuel cell electrical power generation apparatus comprises a fuel cell including a cathode and an anode and an electrolyte matrix containing a quantity of a molten carbonate electrolyte between the cathode and anode; and an electrolyte creepage barrier for substantially preventing electrolyte creepage at the anode of the fuel cell. The electrolyte creepage barrier comprises a relatively thin layer of a material which is poorly wet by the electrolyte disposed in such a way as to substantially prevent electrolyte creepage at the anode of the fuel cell. A related method for blocking creepage of molten carbonate electrolyte in a fuel cell comprises disposing a creepage barrier in such a way as to substantially prevent electrolyte creepage at the anode of the fuel cell.
