Abstract
Fuel cell technology is considered to be the 21st century of choice for clean and efficient power generation technology, due to a fuel cell itself is a very complex physical and chemical process, the input output are different kinds of physical quantities, so a practical fuel cell must have accurate monitoring and control the performance of these physical quantities. Are briefly introduced in this paper the characteristic and principle of the fuel cell, the function of fuel cell system and the fuel cell test system are analyzed, and made a specific fuel cell test system implementation scheme. The system Atmega32 is the core, can finish the collection work of various data quantity very well, theapplication fuel cell inspection meter can complete to the battery voltage and the current measurement. This system has great flexibility, except for the detection of PEMFC, it can also be adapted to different types of fuel cell detection.
