摘要:
The rotor of the present invention is capable of improving magnetic characteristics, general versatility and ease of assembly. The rotor comprises: a rotor shaft; a ring-shaped rotor magnet being disposed coaxially with the rotor shaft; and a non-magnetic cover covering an outer circumference of the rotor magnet. The rotor magnet and the cover are integral-molded with molding resin in a state where an outer circumference of the cover is exposed and both end parts and an inner circumference of the rotor magnet are covered with the molding resin.

In a circuit substrate of an electric water pump, a Hall IC can be mounted on a circuit substrate at an optimum position in a stable and durable state. The electric water pump includes a motor housing, a stator constituted by a stator core covered by a resin insulator and a coil, a circuit substrate, a holder 6 mounted on the circuit substrate, and a Hall IC mounted on the holder. A holder accommodation portion, into which the holder is inserted, is formed in the insulator, the stator is disposed in and fixed to the motor housing, the circuit substrate is appropriately mounted on the motor housing, and the holder 6 is inserted into and supported by the holder accommodation portion.

A fuel cell is protected from performance degradation and damage by determining when an ion exchange resin filter needs replacement before the occurrence of an increase in the electric conductivity of water used in the fuel cell system. The replacement time of the ion exchange resin filter 11 is judged by an ion-exchange capacity judging part 152 on the basis of the result of comparing a reference electric conductivity as preset with the electric conductivity of coolant water circulating in a coolant water cycle as measured by an electric conductivity meter 12 a predetermined time after a coolant water pump 14 starts operation.

A pure-water pipe for fuel cell has an innermost layer made of fluoro resin or polyolefin resin wherein an entire body of the pipe is made of resin and the pipe has a value of (a total thickness of the pipe)/(a thickness of the innermost layer) in a range of 1.1 to 40. The pure-water pipe further has a layer in the outside of the innermost layer which contains one of polyamide, polyester elastomer and polyolefin elastomer or a layer in the outside of the innermost layer which contains non-plastic polyamide. The pure-water pipe further has a low hydrogen-permeable layer in the outside of the innermost layer. The low hydrogen-permeable layer contains ethylene-vinyl alcohol copolymer, polymethaxyleneadipamide, or polybutylene naphthalate.

A system includes a radiator side flow path for supplying a coolant which has cooled a fuel cell stack to a radiator, a bypass flow path for allowing the coolant which has cooled the fuel cell stack to bypass the radiator, a thermostat valve for increasing a flow rate of the coolant flowing through the radiator side flow path in a case where the temperature of the coolant is high as compared to a case where the temperature of the coolant is low, and an electric heater for warming up the coolant. The electric heater is controlled based on an outside atmospheric pressure and on the temperature of the coolant such that the temperature of the coolant flowing into the fuel cell stack is raised in a case where the outside atmospheric pressure is high as compared to a case where the outside atmospheric pressure is low.

In an incubator according to the present invention, a single incubator can be used in any state of four types of devices and thus obviates the need for having many types of devices. A canopy is lowered and raised. In addition to that, a left and right treatment door and a foot end treatment door can be located at their highest positions, lowest positions, and intermediate positions. Also, an infrared heater can be lowered and raised independently of the canopy. This makes it possible to switch the incubator among: a state of an open type incubator; a state of a closed type incubator in which the infrared heater is at its highest position such that the infrared heater can heat the canopy and others; a state of a closed type incubator in which the infrared heater is at its lowest position and this incubator is easily conveyable; and a state of a resuscitation treatment device.

An ion exchange filter for a fuel cell system includes a housing with a fluid flow-in port and a cartridge which is disposed inside the housing and in which an ion exchange resin is filled, the fluid flowing in the cartridge through the flow-in port is filtrated therein by the ion exchange resin and the filtrated fluid flows out through the flow-out port. The housing has a casing having an opened upper end and a lid closing the upper end opening, and the fluid flow-in port has an outer peripheral wall of the casing at a portion above a bottom surface of the cartridge disposed inside the housing and the fluid flow-out port is formed to the lid, and a gap is formed between the housing and the cartridge for flowing the fluid flowing inside the housing through the flow-in port towards the bottom portion of the housing.
摘要:
A fuel cell power plant comprises plural fuel cell stacks (10A–10B) capable of generating power independently, and a warm-up circuit (33) which can independently warm up the fuel cell stacks (10A–10C). A controller (14) estimates a required output power of the power plant within a predetermined time from when the vehicle starts running (S121–S127), and determines the number of fuel cell stacks satisfying the required output power (S106). The controller (14) economizes energy required for warm-up of the fuel cell stacks while providing the required output power by warming up only the determined number of fuel cell stacks before the vehicle starts running.
