... realistic representation of the local activation overpotentials, which leads to improved prediction of the local current density distribution. This leads to high accuracy prediction of temperature distribution ... optimization of future fuel cell with much higher power density, long cell life, and lower cost. In conclusion, the development of physically representative models that allow reliable simulation of the ... durability of fuel cell stack components remains, in most cases, insufficiently understood. Lengthy required testing times, lack of understanding of most degradation mechanisms, and the difficulty of...
