摘要:
A catalytic combustor is configured to accelerate the combustion processing of anode off gas in the combustor to reduce the amount of unburned hydrogen discharged to the outside of the combustor. Anode off gas and cathode off gas discharged from the fuel cell are fed into the catalytic combustor and combusted with a catalyst. Ventilation air is supplied from inside of the fuel cell is also supplied to the catalytic combustor. A portion of the catalytic combustor located upstream of the catalyst inside is divided into an upper flow path and a lower flow path by a partitioning plate and a gas flow passage is provided upstream of the upper and lower flow paths. The cathode off gas is supplied to the gas flow passage.

摘要:
A fuel injector (11) supplies liquid fuel to a catalytic combustor (9) of a fuel reforming device during startup of a fuel reforming device. A controller sets the injection amount (Qf) for liquid fuel to a first injection amount (Qf1) during a predetermined time (t1) after starting fuel injection. After the predetermined time, the injection amount (Qf) is set to a second injection amount (Qf2) which is larger than the first injection amount (Qf1). When the elapsed time after starting fuel injection is smaller than a value (t1), the discharged amount of uncombusted fuel is reduced by setting the injection amount (Qf) to a minimum injection amount (Qf1) which allows ignition and combustion in the catalyst.

A fuel cell system is provided with: a fuel cell generating electrical power by causing hydrogen and oxygen to react; a burner burning discharge cathode gas and discharge anode gas from the fuel cell; a cathode line supplying cathode gas to the fuel cell; an anode line which supplying anode gas to the fuel cell; a cathode switch valve switching the flow of cathode gas in the cathode line; a cathode bypass line connecting the cathode switch valve and the burner; and a controller controlling the cathode switch valve to supply cathode gas via the cathode bypass line to the catalyst burner, without supplying anode gas to the burner, to cause temperature of exhaust gas of the burner to rise so as to reduce an amount of water vapor in the burner to a predetermined level, thereafter stopping the fuel cell system.
摘要:
A controller determines whether a rate of temperature rise on an upstream side of a catalyst portion is at a determination criterion value or higher, and, when the rate of temperature rise on the upstream side of the catalyst portion is at the determination criterion value or higher, the controller determines that a combustor is in an abnormal combustion state. Therefore, an abnormal combustion state of the combustor can be detected before temperature of the combustor becomes high.

A support structure of the present invention includes a fixation member directly or indirectly heated, a supported object supported by the fixation member, and a sliding member provided on an outer periphery of the fixation member, the sliding member being slidable in a longitudinal direction of the fixation member. In the support structure, one fixation part of the supported object is fixed to the fixation member and another fixation part of the supported object is fixed to the sliding member. By this structure, it is possible to avoid concentration of stress and to surely support the supported object to the thermally expanding fixation member.
