A fuel cell system includes fuel cells, a circulation channel of a coolant to cool the fuel cells, and an ion exchange resin provided on the circulation channel to maintain electrical conductivity of the coolant. The coolant contains an additive. The ion exchange resin is prepared so that adsorption of the additive on the ion exchange resin is in a saturated state. A fuel-cell vehicle includes the fuel cell system.

Fuel cell system including coolant additive and ion exchange resin and fuel-cell vehicle

An artificial respiration apparatus includes a frame having a positive pressure input port, a negative pressure input port, an atmospheric port and an output port. A switching member switches between a first state in which the positive pressure input port is connected to the output port while the negative pressure input port is connected to the atmospheric port, and a second state in which the positive pressure input port is connected to the atmospheric port while the negative pressure input port is connected to the output port. A drive unit successively drives the switching operation of the switching member such that the connection between the negative pressure input port and the atmospheric port slightly precedes the connection between the positive pressure input port and the output port.

Oscillating air pressure generator, diaphragm unit, and high-frequency artificial respiration apparatus using the same

The present invention provides an artificial respiration apparatus of a high oscillation type, in which oxygen supply to a patient P and exhaled gas discharge are urged by an oscillating gas having a higher frequency than the cycle of the patient respiration. The apparatus includes a discharge direction regulating mechanism for regulating the exhaled gas to flow only in the discharge direction.

A respirator system is composed of a blower unit for supplying and vacuuming air, a control valve for selecting a positive pressure and a negative pressure from the blower unit to send a vibrating air pressure, a diaphragm for vibrating in connection to the vibrating air pressure to send respiration gas to a patient, and a hollow housing partitioned by the diaphragm into a first pressure chamber cooperating with the vibrating air pressure and a second pressure chamber cooperating with the respiration gas. In addition, the respirator system is further composed of a sensor for sensing the position of the diaphragm in the hollow housing, a pressure regulator for increasing or decreasing the positive pressure and the negative pressure, and a pressure controller for driving and controlling the pressure regulator based on data on the diaphragm position outputted from the sensor. In the respirator system, the pressure regulator increases or decreases the positive pressure and the negative pressure. Thereby, responsiveness can be remarkably improved.
