摘要： A vehicular power system, a vehicle and a method of providing auxiliary power to a vehicle using an auxiliary power unit that uses a molten metal anode solid oxide fuel cell rather than an internal combustion engine. The auxiliary power unit includes a container with numerous fuel cells disposed within it such that when the metal anode is heated, the metal converts to a molten state that can be electrochemically cycled between oxidized and reduced states by oxygen and a fuel present in the molten metal, respectively. The auxiliary power unit further includes a furnace that selectively provides heat to the fuel cells in order to place the anode into its molten metal state. Seals may provide fluid isolation between the molten metal within the container and the ambient environment.

摘要： An apparatus of power generation is provided. The apparatus uses a stack of dense solid oxide fuel cells (SOFC). The exhaust gas generated by a burner of the apparatus enters into the SOFC stack for heating. At the same time, the SOFC stack is heated by the thermal radiation and heat transfer of the burner as well as the thermal convection of gases between the anode and the cathode. Thus, the SOFC stack is heated to reach an operating temperature for generating power without any additional electroheat device. The present invention has a simple structure, flexible operation. Moreover, it increased efficiency, reduced pollutant emission with lowered costs of equipment and operation.

摘要： A fuel cell device with a rectangular solid ceramic substrate extending in length between first and second end surfaces where thermal expansion occurs primarily along the length. An active structure internal to the exterior surface extends along only a first portion of the length and has an anode, cathode and electrolyte therebetween. The first portion is heated to generate a fuel cell reaction. A remaining portion of the length is a non-heated, non-active section lacking opposing anode and cathode where heat dissipates along the remaining portion away from the first portion. A second portion of the length in the remaining portion is distanced away from the first portion such that its exterior surface is at low temperature when the first portion is heated. The anode and cathode have electrical pathways extending from the internal active structure to the exterior surface in the second portion for electrical connection at low temperature.

摘要： In various aspects, systems and methods are provided for operating a solid oxide fuel cell at conditions that can improve or optimize the combined electrical efficiency and chemical efficiency of the fuel cell. Instead of selecting conventional conditions for maximizing the electrical efficiency of a fuel cell, the operating conditions can allow for output of excess synthesis gas and/or hydrogen in the anode exhaust of the fuel cell. The synthesis gas and/or hydrogen can then be used in a variety of applications, including chemical synthesis processes and collection of hydrogen for use as a fuel.
