Development on fuelcell voltage automatic detection system based on virtual instrument

It's necessary to measure each monomer cell voltage of the fuelcell stack in order to ensure fuelcell stack to operate normally. Therefore, a host computer monitoring management software for fuelcell voltage polling measurement based on virtual instrument programming software LabVIEW8.5 was developed. The host computer monitoring management software could show fuelcell's operation voltage to user intuitively in manner of wave illustration, wave form and table through receiving fuelcell's voltage parameters from client computer, and save them with TXT format based on user's demand, thus it is convenient for user to inquire about fuelcell's history and to analyze their status. It is proved that the automatic detection system developed can accomplish sampling, display and saving of fuelcell voltages in real-time after doing experiments on a direct methanol fuelcell.
