Electrochemical impedance spectroscopy (EIS) is an important diagnostic tool for fuel cells. Accurate extraction of physical parameters from spectra remains a significant challenge vehicle The reliability analysis results obtained herein revealed that precise identification middle and low-frequency by traditional equivalent circuit model (ECM) was difficult. However, it determined the distribution relaxation times (DRT) could be used to extract three characteristic peaks EIS data, which...
Sub-zero startup ability remains a key barrier for commercial application of polymer electrolyte fuel cells (PEMFC), especially automotive applications. In order to improve the and durability cells, understanding characteristics mechanisms cold start is essential, here modeling cell plays an important role. this study, one-dimensional model developed simulate start. The includes mass transport phase change, heat transfer electrochemical reaction. Key features such as membrane water local...
Proton exchange membrane fuel cell (PEMFC) has become one of the key power sources for electrical transportation. As demand increases, active area PEMFC becomes larger. However, under same operating conditions and with materials, performance commercial large-area cells (LAFCs) differ from those laboratory-level small-area (SAFCs) due to uneven distribution internal states, such as gas water content. This phenomenon is referred size effect. Investigating mechanism effect essential designing...
Abstract Industrial by-product hydrogen and reformate from ammonia are possible fuels for proton exchange membrane fuel cells (PEMFCs) which may have impurities that damage the performance. This study investigates influence of in anode on performance PEMFCs. Comprehensive electrochemical characterizations were employed to analyze effects varying concentrations relative humidity (RH) levels. The results demonstrate significantly increase electrode activation overpotentials transfer resistance...
In this paper, the rotational magnetic properties of ultra-thin non-oriented silicon steel ST100 (200 Hz - 5 kHz) are measured by novel two-dimensional property tester, with nanocrystalline alloy 1K107B (1 kHz 20 serving as a reference. The anisotropy behavior these materials under varying flux densities is analyzed based on experimental results. change in circular magnetization explained comparing B-H phase difference at different and frequencies. Taking elliptical 1 case study, levels...
