Water management in an AB-PEMFC (air-breathing proton exchange membrane fuel cell) poses a big challenge due to its passive operation. The issue is addressed in a passive way by designing the fuel cell with low thermal conductivity materials. Use of low thermal conductivity materials for cell...

In order to model the liquid water transport in the porous materials used in polymer electrolyte membrane (PEM) fuel cells, the pore network models are often applied. The presented model is a novel approach to further develop these models towards a percolation model that is based on the fiber...

This paper focuses on reviewing the main factors affecting the life time of fuel cells on vehicles. The main difference between fuel cells used in vehicles and fuel cells used as fixed power is the load cycling. Load cycling sometimes leads to water management and gas transport problems, which...

The present work takes part in a global development of reliable and robust tools allowing real-time controlling and supervising of the Têt catchment area, the main river of the Pyrénées-Orientales department (Southern France). The impact of the Têt on the department life is significant and...

This study concerns the use of conductive carbon material with different content and structure to produce carbon fiber paper for use in proton exchange membrane fuel cells, and investigates how changes in the content and structure of the conductive carbon material influence fuel cell performance.

A 50 cm2 commercial PEM fuel cell has been used to investigate the effects of a set of different operating conditions on the resulting liquid water distributions in the cell. A comprehensive matrix of operating conditions was analyzed, varying the reactants relative humidity (anode and...
