Activity Validation of the Synthesized Catalysts in a Fuel Cell Operation

4 Activity Validation of the Synthesized Catalysts in a Fuel Cell Operation 

Many studies have examined various aspects of PEM fuel cell performance as a function of operating conditions [180-182]. Gottesfeld wrote an excellent review of PEM fuel cells components and operation [183]. In addition to experimental characterization, much research has focused on first-principles-based modeling of the PEM fuel cells [184, 185]. Polarization occurs during operation of PEM fuel cells and it dramatically influences both the performance and the commercialization of the technology. In order to systematically improve the efficiency of the fuel cell, a better understanding of the reactions and mass transport in the cell is essential. In this section, the improvement of the MEA performance based on CNTs and CNFs catalysts will be discussed.
