Summary:

Hydrogen is one of the main developed energy in the past years in several areas due to its many advantages. Automotive industry is one of principal applications of this new energy source. To exploit advantages of this energy, researchers make advanced research on this energy sector. However, to ensure an optimal security to final user of hydrogen based vehicles, hydrogen detection devices are necessary to control any risks arising from use of this energy. The growing needs of this booming industry confront us with increasingly severe constraints in terms of performance, cost and reliability to ensure its commercial success. Commercialized sensors being not able to response to automotive industry requirements. It is essential to use alternative technologies which response to different requirements, especially, in terms of reliability and robustness to ensure a successful transition to a new technology based on clean and renewable energy. Several alternative technologies have been proposed in the literature to replace commercialized sensor technologies. One of the main alternative technologies developed is acoustic technology due to its several advantages, especially, in term of robustness. However, this new alternative technology still requires research and development to eliminate its weaknesses in terms of temperature and humidity stability.
