Abstract
The present invention relates to a membrane that includes a porous polymer material made of a polyimide with interconnected macropores and impregnated with protic ionic liquid conductors (CLIP), as well as to the method for manufacturing same and to the uses thereof. The membranes of the invention fulfill the need for membranes including CLIPs, which have good proton-conducting properties as well as good physical properties, in particular high thermal and mechanical stability, in addition to a wide range of electrochemical stability.
