A back-contact solar cell module and a process for making such a solar cell module are provided. The module includes a porous wire mounting layer with a plurality of elongated electrically conductive wires mounted thereon. A polymeric encapsulant layer is provided between a rear surface of solar cells of the module and the porous wire mounting layer and is melted to adhere to the solar cells and penetrate the porous wire mounting layer. Back electrical contacts on the solar cells are electrically connected to the electrically conductive wires through the porous wire mounting layer.

Back contact photovoltaic module with integrated circuitry

A fuel cell includes a direct liquid fuel cell and a humidifier. The direct liquid fuel cell includes an air intake channel for providing oxidant to the fuel cell and an exhaust channel for exhausting depleted oxidant. The humidifier forms a fluid connection between the air intake channel and the exhaust channel.

Method and apparatus for enhancing power density of direct liquid 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.

Hydrogel barrier for fuel cells

A process for making a back-contact solar cell module is provided. Electrically conductive wires of an integrated back-sheet are physically and electrically attached to the back contacts of the solar cells of a solar cell array through openings in a polymeric interlayer dielectric layer using an electrically conductive binder before thermal lamination of the module.

A fuel cell comprises an anode comprising an anode catalyst, a cathode comprising a gas diffusion electrode and a cathode catalyst on the gas diffusion electrode, a microfluidic channel contiguous with the anode, and a liquid comprising fuel in the channel. The concentration of the fuel in the liquid is 0.05-0.5 M.

High efficiency fuel cell system

An electrochemical cell includes an anode including an anode catalyst, a cathode including a cathode catalyst, and a first set of proton-conducting metal nanoparticles between the anode and the cathode, such that the first set of proton-conducting metal nanoparticles is not in contact with the anode. The cathode may be a cathode assembly including a gas diffusion electrode, a cathode catalyst on the gas diffusion electrode, and proton-conducting metal nanoparticles on the cathode catalyst.

Permselective composite membrane for electrochemical cells

An electrochemical cell comprises a first electrode, a second electrode, a porous separator, between the first and second electrodes, a first channel, having an inlet and an outlet, and a second channel, having an inlet and an outlet. The first channel is contiguous with the first electrode and the porous separator, and the second channel is contiguous with the second electrode and the porous separator.

Electrochemical cells

An electrochemical cell includes an anode, a cathode including a gas diffusion electrode and having first and second surfaces, an inlet for gaseous oxidant that is in contact with the first surface of the cathode, and a liquid electrolyte. Water generated at the cathode may be transported by osmosis into the liquid electrolyte. The fuel cell may produce a current density of 200 mA/cmwithout cathode flooding.
