... on a workstation with dual six-core processor (2.66 GHz) and 12 GB of RAM. Simulations were carried out for typical conditions found in an open-cathode PEFC stack and typical fin cooling; the base-case conditions together with the geometry and physical parameters can be found in Table 2 . The model...

... of the fuel cell components, mass flow rate of reactants, water production, heat output, heat transfer and the cooling system. This work is intended to facilitate material and process selection prior to manufacturing alternatives prior to capital investment for wide-scale production. The authors believe...

... model of the PEMFC system is introduced, which has a model for a turbo blower, a membrane humidifier, two cooling circuits, and a PEMFC stack. The thermal efficiency of the PEMFC system for the RPG is very high because it supplies the electricity and hot water to the house. This study is designed...

...Loïc Boulon; Marie-Cécile Péra; Philippe Delarue; Alain Bouscayrol; Daniel Hissel This paper presents a model of a whole polymer electrolyte fuel cell system including the stack, an air compressor, a cooling system, and a power converter. This model allows its integration in a complete hybrid...

... for automotive PEMFCs. A critical review of the recent developments on these topics is presented in this paper. The study covers both the microscopic and macroscopic aspects of the transport within membrane, catalyst layers, gas diffusion layers, and gas channels, and an overview of the current PEMFC cooling...

... in the actual system. The test system consists of a prototype cathode air cooled 30 cell HTPEM fuel cell stack developed at the Institute of Energy Technology at Aalborg University. This fuel cell stack uses PEMEAS Celtec P-1000 membranes and runs on pure hydrogen in a dead-end anode configuration with a purge...

... in Sc Ce Zr O 2 electrolyte upon heating and cooling down from the operation temperatures. DSC data and fraction of the cubic phase for DKKK samples sintered at 1600 ° C upon heating. DSC data are also presented upon cooling of the ceramics. ( a ) Results of the XRD Rietveld...

... cooling performance, and interconnect channels of cross-sectional aspect ratio of ∼ 2 - 3 along with relative anode porous-layer thickness of ∼ 0.5 - 1.5 are seen to provide optimal thermal management and species mass transport benefits in the SOFC module. 19 05 2006 31 08 2006 solid...

... in FEMLAB , which considers the stack geometry, cooling air flow rate and ambient temperature. Both models were validated using the experimental data acquired on a Ballard Nexa 1.5 kWe proton exchange membrane (PEM) system. The results prove that integrated model simulates with accuracy the dynamics...

...), the air preheating, and the fuel cell cooling. In this paper, the impact of heat exchangers on the performance of SOFC, MCFC gas turbine hybrid systems and PEMFC systems is investigated. Several options in terms of cycle layout and heat exchanger technology are discussed from the on-design, off-design...

...M. H. Saidi; A. Abbassi; M. A. Ehyaei In this paper, a 5 kW PEM fuel cell including burner, steam reformer, and water heater for domestic application has been considered. Water is used for cooling of the fuel cell. Cold water is passed through a cooling channel, warmed up and used for domestic...
