Novel analytic method of membrane electrode assembly parameters for fuel cell consistency evaluation by micro-current excitation
Peng Ren,Chen Dongfang,Pucheng Pei,Mário Veverka,Chen Dongfang,Li Yuehua,Wu Ziyao,Lu Zhang,Li Zizhao,Mingkai Wang,He Wang,Wang Bozheng,Xizhong Wang +12 more
TL;DR: In this paper, a novel analytic method of MEA parameters is proposed with high accuracy and stability, which does not require high sampling frequency and data filtering of voltage signals anymore. But the method is not suitable for large-scale fuel cell stacks, and it cannot be applied to evaluate the MEA consistency of a long-time-stored seven-cell stack and recognizes part of the membranes ineffective.

Corrosion of metallic bipolar plates accelerated by operating conditions in a simulated PEM fuel cell cathode environment
TL;DR: In this paper , accelerated stress tests were conducted to reveal the operation-induced corrosion mechanisms of typical SS316L bipolar plates (BPs) in fuel cell stacks to achieve an extremely high power density, and thus suitable for vehicle applications.

Micro-current excitation for efficient diagnosis of membrane electrode assemblies in fuel cell stacks: Error analysis and method optimization
Peng Ren,Pucheng Pei,Dongfang Chen,Yuehua Li,He Wang,Xi Fu,Lu Zhang,Mingkai Wang,Xinwang Song +8 more
TL;DR: In this paper , the micro-current excitation (MCE) method has promising prospects in consistency evaluation due to its capacity in MEA component diagnosis at the stack level, and a detailed error analysis is conducted concerning the decoupling algorithm, the simplified model, and the stack state, demonstrating the significance of error revision for degraded stacks.

Modification of cerebrovascular morphologies during different stages of life
Boyu Zhang,Zidong Yang,Jing Li,Bei Wang,Huazheng Shi,He Wang,Yuehua Li +6 more
TL;DR: Age was found to be a significant predictor for cerebrovascular modifications after adjusting for vascular risk factors and rapid alterations in all three morphological features assessed have been noticed to be associated with aging in the 45–54 subgroup, suggesting the potential importance of the 5th decade for early preservation method for vascular aging.
