Rapid start-up, auxiliary power, and air preheating device of high temperature fuel cell systems

A rapid start-up auxiliary power and air preheating device of high temperature fuel cell systems, being a direct combustion solid oxide fuel cell module formed by combining a metal sheet and a heat-resisting ceramic insulating material, and the rapid start-up auxiliary power and air preheating device comprising a peripheral area and a core area, and the core area including the direct combustion solid oxide fuel cell module, an upper metal plate serving as a cell cathode electrode electricity collecting plate, and a lower metal mesh plate serving as a cell anode electrode electricity collecting plate, wherein the lower metal mesh plate including a flash indentation with a size and a position matched with the direct combustion solid oxide fuel cell module disposed above;

• and a plurality of current collecting ribs disposed at a distal surface in contact with a film electrode module being coupled to the lower metal mesh plate, and two high temperature resisting ceramic insulating rings being disposed around one periphery of the upper metal mesh plate and one periphery of the lower metal mesh plate for preventing a contact between the upper mesh plate and the lower mesh plate metal mesh plates and a metal casing;
• and the peripheral area including an air passage connected to the core area in the device, an inlet passage, an outlet passage, and an igniter, and the inlet passage being a position for flowing in air, and the outlet passage being connected to a system unit for supplying a high temperature gas.
