... with lithium-ion battery (LIB) energy storage and a PV array coupled with regenerative fuel cell (RFC) energy storage. Influence of parameters such as lunar latitude, size, and transient power demand are discussed. In both cases considered, the PV array dominates exergy performance of the overall system...

...) to generate nitrogen enriched air (NEA) for fuel tank inerting. EGSIS is an externally powered device that functionally combines a polymer electrolyte membrane (PEM) fuel cell cathode with a PEM electrolyzer anode. Water management is important in such a PEM-based system because proton transfer requires...

... Abstract Low-temperature fuel cells have the potential to be used in portable and automotive applications, and the direct-methanol fuel cell is a good candidate for such applications as the fuel is in the liquid phase, making it easy to store and handle. Active direct-methanol fuel cells (DMFCs...

... Abstract Solid-oxide fuel cell (SOFC) are among the highest types of fuel cells in terms of efficiency, reaching as high as 65%. However, poor mechanical robustness and thermal cycling stability are the major disadvantages of these fuel cells due to high thermal stresses between layers. A new...

... Abstract The present experimental study aims to determine the effect of two different gas diffusion layers in the performance of a 5-cm 2 proton exchange membrane (PEM) fuel cell. The gas diffusion layers consisted of a carbon cloth gas diffusion (GDL-CT) and a non-woven carbon paper (Sigracet...

... 01 05 2012 The present study is concerned with the dynamic behavior of the liquid water droplets in the water removal process in the serpentine channels of a PEM fuel cell based on computational fluid dynamic (CFD) simulation. The volume of fluid (VOF) model is adopted to trace...

... 01 05 2012 Fuel cells, currently being developed for automotive and stationary applications, require a supply of pressurized air at about 3 bars abs. This is expelled in the reaction products, mainly as water steam and nitrogen, at approximately 100 °C. The power input required...

... 11 09 2009 High temperature fuel cells can be successfully integrated in a simple cycle or in a combined cycle configuration and achieve lower heating value (LHV) efficiencies greater than gas turbines and reciprocating engines. A simple cycle fuel cell system reaches 50 to 51% LHV...

... simulation results. Using the results of PWS measurement at the test bench and the 1-D simulation the usage of PWS in fuel cell applications is discussed, as well. This work results from the collaboration between Josef Bozˇek Research Center and Renault SA. 26 05 2009 1-D code simulation...

... This work focuses on modeling and performance evaluation of an anodic re-circulation system including ejector technology, pre-reformer and solid oxide fuel cells (SOFC). An improved one-dimensional dynamic model of a simple tubular SOFC cycle components in the engineering equation solver (EES...

... Water management is of critical importance in a proton exchange membrane (PEM) fuel cell. Yet there are very limited studies of water transfer through the membrane and no data are available for water transfer due to individual mechanisms through the membrane electrode assembly (MEA...
