Polymer Electrolyte Fuel Cell Model
TL;DR: In this paper, an isothermal, one-dimensional, steady-state model for a complete polymer electrolyte fuel cell (PEFC) with a 117 Nation | membrane is presented, which predicts an increase in membrane resistance with increased current density and demonstrates the great advantage of a thinner membrane in alleviating this resistance problem.

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.
