The Design of Displaying Module about Cell Voltage Monitor System of Fuel Cell

In order to supervise cell voltage of fuel cell real timely and accurately, this paper has designed displaying module in the system of cell voltage monitor. The module was composed by PIC18f258, LCD CA12864F and keyboard. The PIC sent cell voltages and gather information to LCD after filter and statistic of voltage signal. Then, control it by key-press. It has being successfully used in cell voltage monitor system.
