Provided is a trap and method for removing hydrogen sulfide from a gas stream. The hydrogen sulfide trap includes a monolith substrate on which is disposed zinc oxide, and a second metal or oxide thereof. In some aspects, the hydrogen sulfide trap is advantageously incorporated into systems for producing hydrogen for PEM fuel cells.

L'invention concerne une trappe et un procédé permettant d'extraire le sulfure d'hydrogène d'un flux gazeux. La trappe à sulfure d'hydrogène est composée d'un substrat monolithique sur lequel est placé de l'oxyde de zinc et un second métal ou un oxyde de celui-ci. Selon certains modes de réalisation de l'invention, la trappe à sulfure d'hydrogène sera incorporée dans les systèmes de manière avantageuse afin de produire de l'hydrogène pour des piles à combustible PEM.
