Design and development of a 7kW polymer electrolyte membrane fuel cell stack for UPS application

Identification of critical parameters for PEMFC stack performance characterization and control strategies for reliable and comparable stack benchmarking

“…Apart from the costs, the main challenges for competitive fuel cell systems are stack performance and durability [4,5]. All these aspects are examined in many laboratories and improvements are ongoing by component [6,7] and stack design modifications [8][9][10]. The reliability of the stack characterization and of the benchmark results is thereby crucial because many parameters have significant impact on the results and may vary using different test hardware and test procedures.…”

Development of novel proton exchange membrane fuel cells using stamped metallic bipolar plates

“…Under operating conditions of low humidified air and hydrogen, an average temperature of 63 C and normal pressure, this stack produced a current of 30 A (85 W) at an overall voltage of 2.8 V. Furthermore, the effects of oxygen concentrations, current densities and temperatures on the performance were analyzed using three-dimensional CFD. Squadrito et al [7] experimentally investigated the performance of a water-cooled PEM fuel-cell stack with 200 cm 2 of active area and 70 cells. Gore Primea 5621 MEAs, SGL GDLs and graphite BPs were used as components, and both the reactant and coolant channels were serpentine.…”

Design and development of a multipurpose utility AWD electric vehicle with a hybrid powertrain based on PEM fuel cells and batteries

“…It has also been concluded that the use of passive or active hybrid configurations could be determined by the driving conditions and vehicle specifications. Finally, automatic control for PEM fuel cells power systems has also been developed for stationary applications such as CHP units [17,18], and UPS [19,20]. In summary, big efforts are being devoted to fully understand and optimize the different alternatives for hybrid systems, especially in the automotive sector.…”
