The invention relates to a method for preparing a positive electrode for a lithium-sulfur battery, comprising the following steps:

Method for manufacturing an electrode for a lithium-sulfur battery having a large active surface area

A fuel cell including: a membrane/electrode assembly including a proton exchange membrane and including an anode in contact with the membrane, the membrane/electrode assembly including a first active zone covered by the anode, and a first linking zone not covered by the anode; flow guiding plates between which the membrane/electrode assembly is arranged, the flow guiding plates being traversed by at least one first flow collector in communication with the anode, the first linking zone arranged between the first flow collector and the first active zone. The membrane/electrode assembly further includes a first capacitive layer including a mixture of carbon including a BET specific surface area at least equal to 200 m/g and of a proton-conducting material, arranged on the first linking zone.
