20080248343 | MICROFLUIDIC FUEL CELLS - A fuel cell includes an anode, a cathode, a microfluidic channel contiguous with at least one of the anode and the cathode, and a single flowing electrolyte. The flowing electrolyte passes through the microfluidic channel. A method of generating electricity includes flowing the single electrolyte through the microfluidic channel, where a fuel is oxidized at the anode, an oxidant is reduced at the cathode, and the electrolyte comprises the fuel or the oxidant. The flowing electrolyte may pass through the microfluidic channel in a laminar flow. | 10-09-2008 |
20080274393 | HYDROGEL BARRIER FOR FUEL CELLS - A fuel cell includes an anode including an anode catalyst, a cathode, a channel that is contiguous with the anode, and a liquid electrolyte in the channel. The cathode includes a gas diffusion electrode, a cathode catalyst on the gas diffusion electrode, and a hydrogel on the cathode catalyst. The hydrogel is between the anode and the cathode, and includes an aqueous liquid and a polymer. The polymer has an acid capacity less than 0.8 meq/g and/or has no sulfonic acid groups covalently bound to the polymer. A method of generating electricity includes flowing a liquid electrolyte through the channel, oxidizing a fuel at the anode, and reducing a gaseous oxidant at the cathode. | 11-06-2008 |
