摘要： A photoelectrochemical system may be utilized for processing of wastewater to hydrogen. For example, a method for hydrogen production from wastewater may include: providing a photocathode electrically connected by a wire to a photocatalyst, where both the photocathode and the photocatalyst are at least partially immersed in an electrolyte solution that comprises an aqueous fluid having wastewater at least partially dissolved therein; illuminating the photocathode with first light thereby causing the photocathode to generate a first plurality of electron-electron hole pairs, wherein the photocathode comprises a silicon-based heterojunction; illuminating a photocatalyst with second light thereby causing the photocathode to generate a second plurality of electron-electron hole pairs, wherein the photocatalyst comprises a semiconductor; and photochemically converting the wastewater to hydrogen gas and oxygen.

摘要： An electrolysis cell for electrolyzing water into hydrogen and oxygen. The electrolysis cell includes a current collector, a porous transport layer (PTL), and a PTL coating. The current collector may include a flow field plate having lands and channels collectively forming a flow field. The porous transport layer (PTL) includes a PTL surface facing the current collector and including a PTL surface morphology. The PTL coating is deposited on the PTL surface morphology to form contact regions between the flow field plate and the PTL. The PTL includes noncontact regions between the contact regions along the PTL surface morphology. The noncontact regions are spaced apart from the flow field plate.

摘要： A method of forming a hydrocarbon product and hydrogen gas comprises introducing CH4 to a positive electrode of an electrochemical cell comprising the positive electrode, a negative electrode, and a proton-conducting membrane between the positive electrode and the negative electrode. The proton-conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10−2 S/cm at one or more temperatures within a range of from about 150° C. to about 600° C. A potential difference is applied between the positive electrode and the negative electrode of the electrochemical cell to produce the hydrocarbon product and the hydrogen gas. A CH4 activation system and an electrochemical cell are also described.
