摘要:
A carbon monoxide reducing device supplies oxygen to a reformate gas obtained through a reforming reaction so as to oxidize carbon monoxide contained in the reformate gas by means of the oxygen and thereby reduces a concentration of carbon monoxide contained in the reformate gas. This carbon monoxide reducing device is equipped with an oxygen supply amount controller designed to oxidize CO. The oxygen supply amount controller controls an amount of oxygen supplied to oxidize carbon monoxide contained in the reformate gas based on an amount of supply of fuel contributing to the reforming reaction. Thereby, the amount of oxygen for oxidizing carbon monoxide contained in the reformate gas is adjusted appropriately, and a high-quality reformate gas can be obtained.

A shift reaction section 32 is designed to have a maximum capacity of about 40% of the maximum capacity of reforming section 30. When hydrogen-rich gas is supplied to the shift reaction section 32 in excess of its maximum capacity, a blower 46 supplies air to the hydrogen-rich gas in an amount corresponding to the supply of hydrogen-rich gas, and oxidation reaction of carbon monoxide is performed in addition to the shift reaction. By controlling the amount of air supplied, the carbon monoxide concentration at the exit of the shift reaction section 32 is maintained at a concentration less than a predetermined value. As a result, a fuel reformer 20 can be made compact, and at the same time, the energy required to increase the temperature at the time of start up can be reduced.

According to this invention, when initialization of a storage medium such as a flash memory is erase of the data area, the processing can be stopped. When the processing is stopped, at least initialization of the management area has been completed, and processing using the storage medium can be executed. If erase processing is not stopped but proceeds to the end, no erase processing need be performed in writing new data, and high-speed write is promised. For this purpose, when complete formatting is designated, the management area of the file system is first initialized. Then, erase processing for the data area of the file system is executed by a predetermined block size. If it is determined that stop is designated during the data area erase processing, the processing ends, but the management area has already been initialized.

A CDA processing section extracts an unused area of an information recording medium via a disc status management section and a drive control section. The CDA processing section divides the extracted unused areas by a division criteria value MAS, which allows continuous reproduction of a video and audio stream, and reserves areas having the size of the division criteria value MAS as CDAs. This enables continuous reproduction of AV data, and multiple data can be recorded simultaneously.

A technology for preventing degradation of a hydrogen permeable metal layer in a fuel cell 210 is provided. A fuel cell system 200 including a fuel cell 210 with an anode which has the hydrogen permeable metal layer comprises a fuel cell controller 230 for controlling the operation status of the fuel cell system 200, a temperature parameter acquisition section for acquiring a temperature parameter of the hydrogen permeable metal layer, and a hydrogen permeable metal layer degradation prevention section which reduces the hydrogen partial pressure in an anode channel 212 for supplying fuel gas to the anode. If a temperature of the hydrogen permeable metal layer represented by the temperature parameter deviates from a specified temperature range, the fuel cell controller 230 cause the hydrogen permeable metal layer degradation prevention section to operate for preventing degradation of the hydrogen permeable metal layer.

A control device 7 obtains a reformed carbon quantity C supplied to a reform reaction flow channel 21 from a supplied fuel quantity Qf and also obtains a reformed water quantity S supplied to the reform reaction flow channel 21 from a generated power quantity W. Further, it obtains a oxygen consumed quantity consumed through power generation in a fuel cell 3 from the generated power quantity W, a supplied oxygen quantity to be supplied to a cathode flow channel 33 from a supplied cathode gas quantity Qc, and a reformed oxygen quantity O to be supplied to the reform reaction flow channel 21 based on a difference between the supplied oxygen quantity and the consumed oxygen quantity. By correcting a reformed carbon quantity C (delivery of a fuel pump 51) in accordance with the reformed oxygen quantity O, each of O/C and S/C is kept in a target value range.
摘要:
This invention prevents reduction of hydrogen permeability and deterioration in hydrogen separation members that use an oxygen-containing gas as a cathode off gas and a purge gas. Described is a hydrogen separation device that includes a reformed gas passage, a purge gas passage, and a hydrogen separation membrane. A supply of reformed gas flows through the reformed gas passage. A cathode off gas discharged from a fuel cell cathode flows through the purge gas passage to carry hydrogen transmitted through the hydrogen separation membrane to a fuel cell anode. A portion of the hydrogen separation membrane near the supply of the cathode off gas has enhanced heat resistance that prevents deterioration of the hydrogen separation membrane even when hydrogen transmitted through the membrane reacts with oxygen remaining in the cathode off gas to raise the temperature in the vicinity of the portion close to the supply of the cathode off gas.
摘要:
When the hydrogen separating membrane is in a low temperature condition, a lean bus operation is carried out in a reformer in order to conduct warm-up while suppressing generation of hydrogen. At the timing t1 where the temperature of the hydrogen separator membrane has reached a temperature at which hydrogen embrittlement does not occur, reforming is initiated. In such a condition, oxygen is supplied to hydrogen which is permeated through the hydrogen separator membrane for burning the hydrogen, so as to further facilitate the warm-up. At the timing t2 where the temperature has reached an operation temperature, the supply of oxygen in a purge side is stopped so as to stop the burning of hydrogen, and an operation mode is shifted to a normal operation.
