摘要： An exhaust purification device of an engine providing a NO.sub.x absorbent arranged in the exhaust passage. An O.sub.2 sensor generating a current proportional to the air-fuel ratio is arranged in the engine exhaust passage downstream of the NO.sub.x absorbent. The amount of NO.sub.x actually absorbed in the NO.sub.x absorbent at the time of release of the NO.sub.x is calculated on the basis of the output signal of this O.sub.2 sensor. On the basis of this calculated amount of NO.sub.x, correction is made so that the estimated amount of NO.sub.x represents the actual amount of absorption of NO.sub.x. When this corrected estimated amount of NO.sub.x reaches a set value, the action of releasing the NO.sub.x from the NO.sub.x absorbent is carried out.

摘要： An exhaust purification device which is capable of detecting the degree of deterioration of the NOx absorbent or the three-way catalyst arranged in the exhaust passage of an engine. An O.sub.2 sensor whose output current or output voltage is proportional to the air-fuel ratio is arranged inside the exhaust passage downstream of the NOx absorbent or three-way catalyst. The air-fuel ratio of the air-fuel mixture is temporarily changed from lean to rich or from rich to lean to enable the degree of deterioration of the NOx absorbent or three-way catalyst to be detected from the peak value of the output current or voltage of the O.sub.2 sensor during the time when the air-fuel ratio is changed.

摘要： An engine comprising an exhaust passage having therein a NO.sub.x absorbent which absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent is lean and releases the absorbed NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent becomes the stoichiometric air-fuel ratio or rich. A catalyst having an O.sub.2 storage function is arranged in the exhaust passage downstream of the NO.sub.x absorbent. When NO.sub.x is to be released from the NO.sub.x absorbent, the air-fuel ratio of the exhaust gas is made rich to an extent such that the amount of unburned HC and CO is excessive beyond an amount necessary to reduce the whole NO.sub.x.

摘要： An easy-to-assemble structure of a power converter includes a control circuit board, semiconductor modules with power terminals and control terminals extending therefrom, and a capacitor to smooth voltage to be applied to the semiconductor modules. The capacitor includes capacitor devices coupled to the power terminals and voltage measuring terminals joined to electrodes of the capacitor devices. The control terminals and the voltage measuring terminals extend in a direction normal to the surface of the control circuit board. This permits the connections of the voltage measuring terminals and the control terminals with the control circuit board to be achieved simultaneously by bringing them close to the control circuit board from the normal direction.

摘要： An electrolyte layer (121) and a hydrogen-permeable metal layer (122) are fitted in a fitting portion (131) of a low thermal expansion member (130), and a cathode electrode (110) is provided on the electrolyte layer (121). Gas separators (100, 150) are provided such that a low thermal expansion member (130) is held between the gas separators (100, 150). Since the low thermal expansion member (130) is made of metal which has a thermal expansion coefficient lower than that of the hydrogen-permeable metal layer (122), thermal expansion of the hydrogen-permeable metal layer (122) can be suppressed. Accordingly, it is possible to reduce shear stress applied to an interface between the electrolyte layer (121) and the hydrogen-permeable metal layer (122) due to the thermal expansion. It is possible to suppress separation of the electrolyte layer (121) from the hydrogen-permeable metal layer (122) and occurrence of a crack in the electrolyte layer (121).

摘要： A power system of the invention includes fuel cells and a fuel gas generation system that generates a fuel gas to be supplied to the fuel cells. At the time of stopping supply of hydrogen, the fuel gas generation system selectively uses a stop process that replaces hydrogen in a hydrogen separator unit with the air for removal of hydrogen and a pause process that allows hydrogen to remain in the hydrogen separator unit. The stop process is selected when the fuel gas generation system stops the supply of hydrogen for a long time period. The pause process is selected when the fuel gas generation system temporarily stops the supply of hydrogen. The arrangement of the invention desirably shortens a restart time of the fuel gas generation system and reduces a potential energy loss.

摘要： The invention provides an electrolyte membrane that allows an operating temperature of a solid polymer membrane fuel cell to be raised and an operating temperature of a solid oxide fuel cell to be lowered. This electrolyte membrane can be used in a fuel cell that is operable in an intermediate temperature range. The invention also provides a fuel cell using such an electrolyte membrane. The electrolyte membrane has a hydrated electrolyte layer, and dense layers made of a hydrogen permeable material that are formed on both sides of this electrolyte layer. Both sides of the electrolyte membrane are coated with dense layers. Consequently, evaporation of moisture contained in the electrolyte layer is suppressed, and increase in the resistance of the membrane is inhibited. As a result, the range of the operating temperature of the fuel cell can be enlarged.
