Because the parameters needed to be controlled and regulated are many and complex when PEMFC is in operation, there is a need to provide it a stable and reliable test and control platform. As the fuel cell is still in development stage, there is no standard instrument of fuel cell. Domestic and foreign production of test analyzer is quite few; therefore, the Fuel Cell Test Analyzer(for short, FCTA) has a range of issues, such as the relatively backward technology, poor real-time, and the high cost of foreign productions.
