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.
