Title: Hydrogen Gas Leakage Monitoring in EV Fuel Cell by Volumetric Source Reconstruction
Keywords: Sensitivity, Computational modeling, Hydrogen, Fuel cells, R

Abstract: This paper presents a hydrogen gas leakage monitoring system in electrical vehicle (EV) fuel cell pack by source reconstruction algorithm. A distributed array of catalytic type H 2 sensors is considered and a reconstruction approach for precise gas emission source location inside a fuel cell pack enclosure. The reconstruction algorithm is based on a fast interpolation technique suitable for real-time data processing. Estimation of reconstruction method accuracy is made by computational model of hydrogen gas diffusion in air. Sensitivity and sensing upper range analysis of single sensor and sensor array have been performed.
