System Configuration

Fuel Cells

Multiple fuel cells (single cells) are connected in series on the outside of substrate tube (ceramic) to form cell stacks, which is bundled to create cartridges (with outputs of several dozen kW). These cartridges are gathered together and stored in a pressure vessel. This configuration is collectively referred to as a "module." Adopting this sort of layered structure offers easy installation and maintenance. In addition, since electrical output can be adjusted depending on the number of cartridges or modules, it is possible to supply the right amount of electricity as needed.

  • Module
    A structure with cartridges gathered together and stored within a pressure vessel.
  • Cartridge
    A bundle of cell stacks that functions as a bearing member, supplies and discharges fuel and air, and collects current.
  • Cell Stack
    Elements that react to power generation (fuel cell stack of fuel electrodes, electrolyte and air electrodes) are formed on the outer surface of a substrate tube that serves as a structural member made from highly-strengthened ceramic. As elements are connected in a series with inter-connectors made from electronically conductive ceramic, high voltage electrical output can be efficiently collected at low currents.
