A cardiac lead comprising a lead body extending from a proximal end portion to a distal end portion; a cardiac electrode disposed along the lead body; and a coating associated with at least a portion of the electrode, the coating comprises a conductive polymer.

Conductive polymeric coating with optional biobeneficial topcoat for a medical lead

A membrane electrode assembly for use with a direct organic fuel cell containing a formic acid fuel includes a solid polymer electrolyte having first and second surfaces, an anode on the first surface and a cathode on the second surface and electrically linked to the anode. The solid polymer electrolyte has a thickness t: where Cis the formic acid fuel concentration over the anode, Dis the effective diffusivity of the fuel in the solid polymer electrolyte, Kis the equilibrium constant for partition coefficient for the fuel into the solid polymer electrolyte membrane, &#x2111; is Faraday's constant nis the number of electrons released whenmolecule of the fuel is oxidized, and jis an empirically determined crossover rate of fuel above which the fuel cell does not operate.

Fuel cell membranes and crossover prevention

A method of electrolytic synthesis comprises applying a potential between a first electrode and a second electrode. The first electrode is in contact with a first fluid stream in a channel, the second electrode is in contact with a second fluid stream in the channel, and the first steam and the second stream are in parallel laminar flow in the channel.

Microfluid device and synthetic methods

A method for transporting a gas to an electrode in a fuel cell is provided, whereby the gas is dissolved in an emulsion comprising a fluorinated hydrocarbon, a surfactant and an aqueous electrolyte with a pH of at most 4 or at least 9, and the emulsion is contacted with the electrode.

Emulsions for fuel cells

A direct organic fuel cell includes a formic acid fuel solution having between about 10% and about 95% formic acid. The formic acid is oxidized at an anode. The anode may include a Pt/Pd catalyst that promotes the direct oxidation of the formic acid via a direct reaction path that does not include formation of a CO intermediate.
