The invention relates to an assembly for the wireless supply of electric energy to a number of sensors and/or actuators (1.1 to 1.s) which are mounted onto a machine. A micro fuel cell (6) with a corresponding fuel reservoir (5) is integrated into the sensors and/or actuators, which converts the stored fuel, preferably methanol, into electric energy for supplying to the sensors. The invention also relates to a sensor or an actuator, comprising an integrated micro fuel cell (6) with corresponding fuel reservoir (5), which converts the stored fuel into electric energy for supplying the sensors. The invention further relates to a system for a machine (2) which has a number of sensors and/or actuators, in particular, for an automated production machine, whereby the sensors and/or actuators (1.1 to 1.s) are equipped with a transmitter or a receiver or a transceiver (3) which communicates with a central transmitter or receiver or transceiver that is connected via radio signals to a process control computer (4) of the machine (2). In said system, a micro fuel cell (6) with a corresponding fuel reservoir (5) is integrated into the sensors, which converts the stored fuel into electric energy for supplying to the sensors.

There have been insufficient highly reliable responses appropriate to the causes of power generation abnormalities in fuel cells that generate power by supplying an oxidizing agent containing oxygen to the cathode and by supplying a fuel gas containing hydrogen to the anode. In order to overcome this problem the invention provides for a fuel cell power generation system equipped with a means that includes AC signal generation block 503 and load 502 that varies the load current for fuel cell 501, which operates to generate power; voltage measurement block 504 that measures the voltage response to the load current variation; impedance measurement block 505 that computes the impedance of fuel cell 501, based on the results of the measurement of the voltage response; and fuel cell control block 506 that varies the operating conditions of fuel cell 501, by utilizing the impedance computation results.

摘要:
A mobile vehicle power supply system and an electricity exchanging system enhance the economic viability of different modes of transportation that incorporate generators, such as electric motors and fuel cells, to generate electricity. The power supply system provides for the off-board use of the electric power generated by the generator of a mobile vehicle, such as an electric car. Off-board use, or use remote from the vehicle, of the electrical power includes the delivery of power to a remote site. Off-board stations are provided for delivery of fuel to the vehicle and/or for receiving the electrical power generated by the fuel cell. The off-board station and the vehicle are appropriately equipped for quick and easy interconnection such that electrical power can be exchanged between the vehicle and off-board station and the electricity exchanging system. The electricity exchanging system is configured for installation at numerous locations for allowing a mobile vehicle operator to purchase or sell electricity. The operator employs a user authorization element to assist the recording or tracking of electricity exchanged between the vehicle and the electricity exchanging system.
