A fuel cell having good resistance to compressive creep includes electrodes having a superstructure of porous electrically conductive foam with surface sections adjacent to opposing surfaces of an electrolyte matrix impregnated with electrode catalyst materials. The catalyst materials are affixed in sections contiguous to an inner major surface by sinter bonding, electrochemical bonding or restrictive interstitial spacing. The outer sections of the porous plaque thickness are reserved for gas distribution to the electrode catalyst. Oxidant and fuel gases can be separately manifolded into alternate sides of a fuel cell stack by sealing opposing edges of the porous plaques containing the anode material in one set of opposing side surfaces and sealing opposing edges of the porous plaque containing cathode material in alternate side surfaces of the stack.

An electrochemical device comprising alternating layers of positive and negative electrodes separated from each other by separator layers. The electrode layers extend beyond the periphery of the separator layers providing superior contact between the electrodes and battery terminals, eliminating the need for welding the electrode to the terminal. Electrical resistance within the battery is decreased and thermal conductivity of the cell is increased allowing for superior heat removal from the battery and increased efficiency. Increased internal pressure within the battery can be alleviated without damaging or removing the battery from service while keeping the contents of the battery sealed off from the atmosphere by a pressure release system. Nonoperative cells within a battery assembly can also be removed from service by shorting the nonoperative cell thus decreasing battery life.

A thin, flexible, porous ceramic composite (PCC) film useful as a separator for a molten-salt thermal battery comprises 50% to 95% by weight of electrically non-conductive ceramic fibers comprising a coating of magnesium oxide on the surface of the fibers in an amount in the range of 5% to 50% by weight. The ceramic fibers comprise AlO, AlSiO, BN, AlN, or a mixture of two or more of the foregoing; and the magnesium oxide coating interconnects the ceramic fibers providing a porous network of magnesium oxide-coated fibers having a porosity of not less than 50% by volume. The pores of the film optionally can include a solid electrolyte salt. A laminated electrode/PCC film combination is also provided, as well as a thermal battery cell comprising the PCC film as a separator.

A thin, fibrous ceramic article useful as a separator for a molten-salt thermal battery. A film of ceramic fiber and a bonding constituent that in processing enhances the strength flexibility and molten electrolyte retention of the film when used as a separator layer. The bonding constituent becomes a significant portion of the separator, such that the separator's chemical properties are a reflection of the binder. MgO is a preferred binder, but other electrically-insulating ceramics, e.g., AlN, are available. The ceramic fiber separator becomes a carrier element in a fabrication process, which allows the formation of dense electrode without the use of high-tonnage hydraulic presses.
