(US6074771-A)   NOVELTY - An electrical power generating device has ceramic composite cells each with a cathode and anode. The cells are connected in series and are surrounded by shock absorbing and insulating materials. An exhaust fan, fuel supply e.g. methane gas and controller e.g. programmable computer with user interface are required. A container will have passageways for air ingress and egress and electrical power output terminals. When stacked, the cells (12) are electrically connected via contact layers (112) on an embossed bipolar foil. Incoming air flows in the plenum next to the cathode (16). The anode (18) is in a gas tight plenum where energy is generated.    USE - Economical and readily portable production of heat or electricity from low power to megawatts e.g. for electrically powered vehicles, generation of power from methane gas produced in landfills, military aircraft, life support systems and in unmanned aerial vehicles.    ADVANTAGE - Provides a rugged stationary, vehicular or portable, efficient, economical, relatively lightweight device capable of delivering power of megawatt output with reduced pollutant emission.
