The invention pertains to an enzymatic biocathode containing biomass based on glucose, monosaccharide, ketone or aldehyde, characterized in that it comprises: - a collector conductor support; - conductive particles disposed on and connected to said collector conductor support; - an aldose reductase disposed on said conductive particles, being connected thereto by adsorption and accessible at the surface to the glucose, monosaccharide, ketone or aldehyde reagent that is to be reduced when the biocathode is operational. L'invention porte sur une biocathode enzymatique à biomasse à base de glucose, de monosaccharide, de cétone ou d'aldéhyde caractérisée par le fait qu'elle comporte : - un support conducteur collecteur; - disposées sur ledit support conducteur collecteur et étant liées avec lui, des particules conductrices; - une aldose réductase disposée sur lesdites particules conductrices, étant liée avec elles par adsorption et étant accessible en surface au réactif glucose, monosaccharide, cétone ou aldéhyde destiné à être réduit lors du fonctionnement de la biocathode.
