Electric power

EIS study to analyse the influence of mechanical compression on the global PEM fuel cell performance

Proper clamping pressure is needed to guarantee the gas-tightness of PEMFC assembly and to enhance the contacts between components. Nevertheless, excessive mechanical load can deteriorate the cell performance, particularly by reducing the porosity…

Stack-level diagnosis of proton exchange membrane fuel cell by the distribution of relaxation times analysis of electrochemical impedance spectroscopy

A comprehensive Distribution of Relaxation Times (DRT) analysis is carried out for a proton exchange membrane fuel cell (PEMFC) in this research, to achieve stack-level fault diagnosis by Electrochemical Impedance Spectroscopy (EIS). The durability…

Detection of atypical attentional behaviors in young subjects

Background: Vigilance ability refers to the accuracy and speed with which a person performs a cognitive-motor task, either voluntarily (endogenous mode) or following a warning stimulus (exogenous mode). In the context of a force production task, our…

Generalized performance criteria for identified models

It is shown that some usual criteria evaluating the performances of an identified model with respect to experimental data, like the FIT criterion, can be not well-suited to fast sampled systems. This leads to propose some generalized criteria where…

Encoding the Latent Posterior of Bayesian Neural Networks for Uncertainty Quantification

Bayesian Neural Networks (BNNs) have long been considered an ideal, yet unscalable solution for improving the robustness and the predictive uncertainty of deep neural networks. While they could capture more accurately the posterior distribution of…
