Abstract:
|
This article presents different diagnosis tools for Proton Exchange Membrane Fuel Cells
based on the analysis of their dynamic evolution when the humidification of the inlet gases is
interrupted. The diagnosis is aimed to know the internal state of the fuel cell with respect to the water
distribution. The proposed diagnosis procedures combine the information of the time response with
that extracted from Electrochemical Impedance Spectroscopy and consist in monitoring the evolution
of a set of performance indicators during the humidification interruption. The article presents a study
for the selection of these performance indicators, which are related to the physical phenomena inside
the PEMFC, and describes the patterns that correspond to proper or improper water distribution. |
