IPC: H01M8/04
Filed: 1986-01-17
Abstract: PURPOSE:To make it possible to operate a fuel cell without the fear of happening of the local lack of the gas due to the variation of the performance of the cell induced in the manufacture or the deviation of the gas flow by operating the cell under a low load condition so as the temperature of the reaction gas supplied to the cell body is lower than that under a high load and the oxidizer or the fuel supplied to the cell body is diluted. CONSTITUTION:The electric signal from a voltage and current detector 14 attached to the cell body 1 is picked up in the upper control device 16, and according to the inlet temperature pattern of the reaction gas corresponding to the preset load the signal of the set temperature is sent to a gas temperature control device 15 provided in the air line 7a of the cell inlet to control the temperature of the gas, so that the unit cell voltage is controlled to be lower. A control device 22 of the recirculation system opens a stop valve 20, operates a recirculation blower 12, and controls the recirculation amount automatically with a flowmeter 20 and a flow control valve 21 according to the recirculation gas amount command. Thereby the low load operation of the cell can be performed under the condition so as the signal from the voltage and current detector 14 provided on the cell body 1 is lower than the voltage corresponding to the allowable unit cell voltage and the required load is satisfied.

Abstract: PROBLEM TO BE SOLVED: To shorten the response times of equipment mounted on electric cars by exchanging information between a central device and terminal devices at a certain cycle and by using a token passing transmission system in which the information is shared by the central and terminal devices. SOLUTION: A central device 7 transmits all its data to the terminal devices 1 of all of electric cars and, when the data transmission ends, transfers its transmission right to the terminal device 1 of the car No.1. The data of the terminal device of the car No.1 are transmitted to the central device 7 and the terminal devices 1 of all of the cars except itself and its transmission right is transferred to the terminal device 1 of the car No.2 upon the end of the transmission. The terminal device of the car No.2 transmits the data to the central device 7 and the terminal devices 1 of all of the cars except itself. The data transmissions are performed to the terminal device 1 of all the cars and the central device 7 and, when the transmission right is transferred to the terminal device 1 of the last car, the central device 7 regains the right and transmits the data in the same manner.  This system enables a countermeasure for a failure to be performed speedily in accordance with a program installed in advance.

The thicknesses of the metallic films are found from the correlation between the then measured values of the thicknesses and sheet resistances. Therefore, the thicknesses of the metallic films can be measured easily with high accuracy by a method which does not required the contact with a device pattern and does not destroy the wafers.
