摘要:
A fuel cell cooling device includes a plurality of plate-like fuel cell units arranged in a vertical stack and having singly interspersed therein cooling plates. A main coolant pipe supplies coolant at a pressure above the saturation point thereof to the cooling plates through corresponding inlet cooling pipes. A throttle is provided in each inlet cooling pipe to produce a pressure drop such that coolant entering a cooling plate is at a pressure below the saturation point thereof.

A fuel cell manifold mounted airtightly on the side walls of a fuel cell stack, the manifold comprising a seal layer covering the periphery of a wall of the fuel cell stack, a frame-shaped seal spacer having one side mounted airtightly on the seal layer and penetrated by a pipe carrying a cooling solution or electrolyte, and a box-shaped manifold cover mounted airtightly on the opposite side of the seal spacer. A second embodiment employs a hollow seal spacer that functions in place of the pipes carrying cooling solution or electrolyte.

When a seat belt 14 is unfastened, reactive force against treading pressure on the accelerator pedal is enhanced by a pedal reactive force enhancer 10 even if a driver tries to drive a vehicle by turning on an ignition switch 18 and pressing on the accelerator pedal. Thus, it is possible to prompt the driver to fasten the seat belt. When the seat belt is unfastened in an emergency, although the reactive force against treading pressure on the accelerator pedal is enhanced, the driver can drive the vehicle by pressing the accelerator pedal harder. In this way, the driver can deal with such emergency.
摘要:
A system constituted at a relatively large capacity and low output first battery such as a fuel cell, a smaller capacity and higher output second battery, and a current-limiting circuit for restricting the maximum discharge current of the first battery to a predetermined value slightly above the open-circuit voltage of the second battery, which circuit consists of a measuring circuit for measuring the discharge current, a signal generating circuit for providing a reference signal representing the predetermined current, a comparator for the comparison between the reference signal and the measured current and a current flow control circuit operated by the output of the comparator.
摘要:
In a method and apparatus for starting an alcohol engine equipped with a starting motor, alcohol is converted into a high-temperature gaseous mixture containing a relatively highly volatile substance. The gas is cooled to provide a liquid condensate containing the relatively highly volatile substance. The liquid condensate is supplied to the engine as fuel when the starting motor is in operation.
摘要:
A fuel sensor for sensing methanol in methanol-mixed fuel, which comprises a structure which defines a fuel passage through which the mixed fuel flows, an electrode assembly including a pair of probe portions which are exposed to the fuel passage, and an electric circuit causing the paired probe portions to exhibit positive and negative characteristics respectively in the mixed fuel. At least the positive probe portion is intimately covered with an electrically insulating film.

A fuel gauge system is disclosed, which includes a first device capable of visually indicating the amount of the mixed fuel in the container; a second device for detecting a real amount of the fuel in the container; a third device for detecting the mixing ratio of compositions in the mixed fuel; a fourth device for determining a critical effective amount of the mixed fuel in accordance with the fuel mixing ratio detected by the third device; a fifth device for judging whether the real amount is less than the critical effective amount or not; a sixth device for determining, based on the fuel mixing ratio detected and the real amount, a value corresponding to a calorific power possessed by the mixed fuel in the container; and a seventh device for controlling the first device in such a manner that, when the real amount is less than the critical effective amount, the first device indicates the value corresponding to the calorific power possessed by the mixed fuel in the container, and when the real amount is not less than the critical effective amount and the container is filled with the mixed fuel, the first device indicates the real amount of the mixed fuel by volume.

The disclosure relates to a hybrid electric drive including a battery (E-battery) having high specific energy and a battery (P-battery) having a high specific power. These two batteries are electrically circuited with two armature coils connected to a motor shaft of a motor. The two armatures are electrically insulated from each other so that the batteries having different characteristics are electrically insulated from each other.
摘要:
A plurality of fuel-cell stacks operated in electrically parallel connection are individually controlled for amounts of reaction gases fed thereto corresponding to ratios of allotment of load thereto such that each of the stacks can maintain standard gas utilization factor. Among the fuel-cell stacks operated in parallel connection, those stacks which have particularly small ratios of allotment of load are controlled so that their gas utilization factors are changed to be decreased, thus controlling the amounts of the reaction gases to be increased.
摘要:
Herein disclosed is a cell stack assembly structure for a fuel cell, comprising a plurality of units each of which is composed of a plurality of cell elements laminated in advance and which are stacked and fastened under a predetermined pressure to construct a cell stack assembly. Each of a plurality of end plates is interposed between any adjacent two of the units. Removable pressure means are provided for fastening under a predetermined pressure any two of the end plates, that are positioned at the two ends of a corresponding one of the units.
