Disclosed is a method for electrical supply of an apparatus by a system including an intermittent electrical source, electrical storage unit, a fuel cell, and an electrochemical unit for generating the fuel. The method includes steps of: determining a power balance of the system depending on the power consumed by the apparatus and supplied by the intermittent electrical source; receiving data representative of the stability of the power balance during a safety period; controlling the fuel cell and the electrochemical unit: to activate the electrochemical unit if the power balance is greater than a first threshold and the data are not characteristic of a subsequent decrease in the power balance; activating the fuel cell if the power balance is less than a second threshold, which is less than the first threshold, and the data are not characteristic of a subsequent increase in the power balance.

Method for electrical supply of an apparatus by an autonomous hybrid station

The invention relates to a method for producing carbon electrodes by deposition on a substrate, to produce a fuel cell. The method comprises the steps of alternately and/or simultaneously depositing porous carbon and a catalyst onto the substrate by plasma spaying in a vacuum chamber. The catalyst is used to accelerate at least one of the chemical reactions that takes place in the fuel cell. The thickness of each layer of porous carbon is chosen so that the catalyst deposited on this carbon layer is distributed essentially throughout this layer, thereby by providing a layer of catalyzed carbon. The total thickness of catalyzed carbon in the electrode is less than 2 micrometers, and preferably equal to no more than 1 micrometer.
