Abstract

L’invention concerne une électrode à air (1) comprenant : - un collecteur de courant (10) présentant deux faces principales opposées ; - une couche catalytique (20) s’étendant sur une première face principale (11) et destinée à être en contact avec une solution contenant un électrolyte ; - une couche de diffusion (30) s’étendant sur la deuxième face principale (12) et destinée à être en contact un gaz contenant de l’oxygène. Selon l’invention, l’électrode à air comprend un joint (40) étanche à la solution et électriquement conducteur, bordant la couche catalytique et imprégnant au moins partiellement le collecteur de courant.
