Optical fuel cell stack cell voltage monitor |
摘要 |
A voltage monitoring system for measuring the voltage of the fuel cells in a fuel cell stack that employs optical devices for providing an optical signal of the measured voltages, where one or more of the fuel cells power the optical devices. A surface mount device is electrically coupled to opposing plates in the stack, or opposing plates over a plurality of cells in the stack. The surface mount device includes a bonded contact and a spring contact to provide the electrical connection. A detector is positioned remote from the stack that receives the optical signals and converts them back to electrical signals indicative of the voltage.
