Partial flooding and its effect on the performance of a proton exchange membrane fuel cell
TL;DR: In this article, a partial flooding model was proposed to investigate the effect of the porosity on the performance of a proton exchange membrane fuel cell (PEMFC), and the results showed that high temperature is conducive to the suppression of flooding at low relative humidity, and flooding would lead to the deterioration of mass transfer due to a porosity decrease of gas diffusion layer, especially at high current densities.

A water and heat management model for proton-exchange-membrane fuel cells
Trung Van Nguyen,Ralph E. White +1 more
TL;DR: In this paper, a water and heat management model was developed and used to investigate the effectiveness of various humidification designs for proton-exchange-membrane fuel cells and showed that at high current (> 1A/cm[sup 2], ohmic loss in the membrane accounts for a large fraction of the voltage loss in a cell and back diffusion of water from the cathode side of the membrane is insufficient to keep the membrane hydrated.
