Thin-film catalyst layers for polymer electrolyte fuel cell electrodes
TL;DR: In this paper, the Pt/C catalyst layer of polymer electrolyte fuel cell electrodes have been developed that substantially increase the utilization efficiency of the catalyst, and the performance of fuel cells based on the thin film catalyst layers are comparable with those of gas diffusion electrode designs that utilize several times as much platinum, thus the specific catalysts in the new structures are significantly higher.

Transport in Polymer-Electrolyte Membranes I. Physical Model
Adam Z. Weber,John Newman +1 more
TL;DR: In this paper, a physical model of polyelectrolyte membranes is developed that is semiphenomenological and takes into account Schroeder's paradox, and two different transport mechanisms are presented and discussed.

Transport in Polymer-Electrolyte Membranes II. Mathematical Model
Adam Z. Weber,John Newman +1 more
TL;DR: In this paper, a mathematical model is developed that is based on the previous physical model for both the vapor and liquid-equilibrated transport modes as well as when they both occur.

Characterization of gas crossover and its implications in PEM fuel cells
TL;DR: In this paper, an in-situ electrochemical technique has been applied to determine the magnitude of the hydrogen crossover over a range of relevant fuel cell operating temperatures and pressures, and a mathematical model is developed to predict the extent of nitrogen accumulation along the anode flow fields, and fuel recycle as a mitigation method is simulated by improving hydrogen distribution.
