Abstract： |
A flooding diagnosis method of hydrogen/oxygen proton exchange membranes fuel cell, whose characteristics are that: the computer acquire pressure drop of hydrogen in the practical condition by two hydrogen pressure sensor installed on the air exhausting outlet, then compare it with the one calculated by the computer, if the pressure drop measured practically is beyond the reasonable range, the computer will alarm , notify for taking the practice for water exhausting. It can discover the flooding tendency, alarm in time when there is too much water is flow field in stack. |
