Une \u00e9quipe de recherche internationale dirig\u00e9e par l’Universit\u00e9 de Berne a r\u00e9ussi \u00e0 mettre au point un nouveau proc\u00e9d\u00e9 applicable industriellement et pouvant \u00eatre utilis\u00e9 pour mieux optimiser les v\u00e9hicules aliment\u00e9s par des piles \u00e0 combustible sans \u00e9missions de CO\u2082.<\/h4>\n

Les piles \u00e0 combustible gagnent en importance en tant qu’alternative \u00e0 l’\u00e9lectromobilit\u00e9 sur batterie dans le trafic routier, d’autant plus que l’hydrog\u00e8ne est un vecteur d’\u00e9nergie CO\u2082 neutre s’il est obtenu \u00e0 partir de sources renouvelables. Pour fonctionner efficacement, les piles \u00e0 combustible ont besoin d’un \u00e9lectrocatalyseur qui am\u00e9liore la r\u00e9action \u00e9lectrochimique dans laquelle l’\u00e9lectricit\u00e9 est produite.<\/p>\n

Une \u00e9quipe internationale du D\u00e9partement de Chimie et de Biochimie (DCB<\/a>) de l’Universit\u00e9 de Berne<\/a> a r\u00e9ussi \u00e0 utiliser un proc\u00e9d\u00e9 sp\u00e9cial pour produire un \u00e9lectrocatalyseur sans vecteur carbone, qui, contrairement aux catalyseurs existants, se compose d’un mince r\u00e9seau m\u00e9tallique et est donc plus durable. L’\u00e9tude est le fruit d’une collaboration internationale entre la DCB et, entre autres, l’Universit\u00e9 de Copenhague et l’Institut Leibniz pour la Science et la Technologie du Plasma, qui a \u00e9galement utilis\u00e9 l’infrastructure de la Swiss Light Source (SLS<\/a>) \u00e0 l’Institut Paul Scherrer.<\/p>\n

Une technologie pouvant \u00eatre appliqu\u00e9e industriellement<\/h4>\n

\u00ab\u00a0Cette technologie est \u00e9volutive sur le plan industriel et peut donc \u00eatre utilis\u00e9e pour des volumes de production plus importants, par exemple dans l’industrie automobile\u00a0\u00bb, explique Matthias Arenz, chef d’\u00e9quipe de ce projet au DCB \u00e0 Berne. Ce proc\u00e9d\u00e9 permet d’optimiser encore davantage la pile \u00e0 combustible \u00e0 hydrog\u00e8ne pour son utilisation dans le trafic routier. \u00ab\u00a0Nos d\u00e9couvertes sont par cons\u00e9quent importantes pour la poursuite du d\u00e9veloppement de l’utilisation durable de l’\u00e9nergie, en particulier au vu des d\u00e9veloppements actuels dans le secteur de la mobilit\u00e9 des poids lourds\u00a0\u00bb.<\/p>\n","protected":false},"excerpt":{"rendered":"
