A process for depositing a metal-adhesive, hydrophobic and electrically conductive coating based on electrically conductive microparticles and on a polymer matrix P comprising at least one thermoplastic fluoropolymer P1 and a thermosetting resin P2, comprises: in a first container, dissolve the polymer P1 in an organic solvent; in a second container, disperse the electrically conductive microparticles in an organic solvent; add, in the first container, the thermosetting resin P2 in the liquid state; mix the contents of the containers, then deposit the mixture on the substrate; crosslink the resin P2 and remove the solvents, to obtain a first coating; then impregnate the surface of the substrate with an additional resin solution P2 dissolved in a third solvent, which is a solvent of the resin P2 and a non-solvent of the polymer P1; eliminate the third solvent and crosslink while compressing the additional resin P2 in order to obtain the targeted final coating.

A direct alcohol fuel cell having an inner housing, and a proton exchange membrane separating an anode section from a cathode section. The anode section contains an anode collection element electrically connected to an anode catalyst that is in diffusive communication with a fuel supply. The cathode section contains a cathode collection element having one or more ventilation holes is electrically connected to a cathode catalyst. An oleophobic filter and/or an anion-exchange membrane is provided, which cathode catalyst via the one or more ventilation holes and the oleophobic filter and/or the anion-exchange membrane is in diffusive communication with a gaseous oxidant. The inner housing has a bottom and walls extending from the bottom to contain the anode section, the PEM and the cathode section, the bottom and/or the walls having holes allowing fluid communication from a fuel supply to the anode section. The fuel cell is suited for microelectronic devices.

Methods and systems are provided for manufacturing a membrane separator for a redox flow battery. In one example, the membrane separator is fabricate by a calendering process. The membrane separator may be configured with a polymer network to provide selectivity for ion transport across the membrane separator. The membrane separator may be further adapted with an integrated spacer in contact with a negative electrolyte.
