摘要

摘要本文研究了基于燃料电池的电流、电压、氢气流量等测量参数的谱域及其时域表示，提取了它们的谱域特征。此外，考虑到将氢气流量与电池电流定义为一个输入输出对的简化传递函数方法，得到了更详细的结果。因此，在工艺、测量电路和数字化设备的影响下，对燃料电池的光谱部分进行了分类。在非常小的频率(<15 Hz)下定义的过程噪声可以解释为燃料电池中出现的各种物理和化学相互作用的影响。此外，本研究还详细分析了燃料电池的电流、电压和氢流量的光谱特性。

Noise identification based on spectral analysis and noisy transfer function approach for fuel cells

Abstract In this study, some measurements like the current, voltage and hydrogen flow based on the fuel cell are investigated in spectral-domain as well as their time-domain representations and then, their spectral properties are extracted. Besides this, taking the simplified transfer function approach into account, which is defined between the hydrogen flow and current of the cell as an input-output pair, more detailed results are obtained. Therefore, the spectral parts of the fuel cell are put into categories under the impacts coming from the process, measurement circuits and digitizers. The process noise to be defined at very small frequencies (<15 Hz) can be explained as the effects of the various physical and chemical interactions emerging in the fuel cell. Moreover, this study analysed the spectral characteristics of fuel cells for current, voltage and hydrogen flow in detail.

期刊介绍： Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
