摘要： A high-temperature fuel cell system (100) includes a reformer (2) that reforms a hydrocarbon-based raw fuel to generate a reformed gas containing hydrogen, a fuel cell (6) that generates power by using the reformed gas and an oxidant gas, and a burner (20) that heats the reformer (2). The burner (20) includes an anode-off-gas gathering portion (22) that has an anode-off-gas ejection hole (21) and at which an anode off-gas discharged from an anode of the fuel cell (6) gathers. The anode-off-gas gathering portion (22) surrounds a first cathode-off-gas passing area (23) through which a cathode off-gas discharged from a cathode of the fuel cell (6) passes. The anode-off-gas ejection hole (21) is formed such that the anode off-gas ejected upward from the anode-off-gas ejection hole (21) approaches the cathode off-gas passing upward through the first cathode-off-gas passing area (23). The anode off-gas ejected from the anode-off-gas ejection hole (21) and the cathode off-gas that has passed through the first cathode-off-gas passing area (23) are burned.

摘要： A compression apparatus includes at least one compression unit including an electrolyte membrane, an anode provided on a first principal surface of the electrolyte membrane, a cathode provided on a second principal surface of the electrolyte membrane, an anode separator stacked on the anode, and a cathode separator stacked on the cathode, a voltage applier that applies a voltage between the anode and the cathode, an anode end plate provided on the anode separator located at a first end in a direction of stacking, a cathode end plate provided on the cathode separator located at a second end in the direction of stacking, and first and second plates provided between the cathode end plate and the cathode separator located at the second end. The compression apparatus causes, by using the voltage applier to apply a voltage, protons taken out from an anode fluid that is supplied to the anode to move to the cathode via the electrolyte membrane and produces compressed hydrogen. The first plate has formed therein a first space in which to store a cathode gas containing the compressed hydrogen. The second plate is provided with a first manifold through which the cathode gas flows and a first communicating path through which to lead, to the first space, the cathode gas having flowed in from the first manifold.
