Abstract: La présente invention concerne un humidificateur par échange membranaire qui comprend un polymère microporeux et un additif hydrophile. En fonctionnement, cette membrane possède de préférence des propriétés de perméance favorables pour l'eau et elle empêche la transmission de gaz réactif et d'autres composants. Cette membrane convient même quand elle est perméable à l'état sec aux gaz humides ou secs présents dans l'humidificateur, et/ou quand ces gaz humides ou secs sont de compositions différentes. En mouillant cette membrane, on peut réduire la transmission de gaz à travers la membrane à un niveau acceptable par la présence d'une quantité d'eau liquide dans le gaz humide. Cet humidificateur est utile dans les systèmes de pile à combustible dans lesquels un flux d'alimentation de gaz réactif, tel que le flux d'alimentation d'oxydant, est humidifié principalement par de la vapeur d'eau d'un flux d'évacuation de réactant de pile à combustible. Cet humidificateur convient particulièrement pour une utilisation en association avec des systèmes de pile à combustibles à polymère solide. Les propriétés de soudage et les propriétés mécaniques améliorées de cette membrane permettent un agencement d'humidificateur plus simple.
