CN_110998745_A

Resumen de: WO2019012120A1

A method of producing energy from condensed hydrogen clusters created from the desorption of hydrogen atoms from a primary material. The method of producing energy from condensed hydrogen clusters generally includes positioning at least a desorbing side of a primary material within a sealed reactor chamber. Mono-isotopic hydrogen atoms are absorbed by the primary material. Condensed hydrogen clusters are formed from the desorption of the hydrogen atoms from the primary material. Stability of the condensed hydrogen clusters is maintained by prevention of covalent bond formation and recombination into hydrogen molecules. A nuclear reaction and spallation of the stable condensed hydrogen clusters is initiated to produce reaction products. Energy may be harvested from the reaction products, such as through a coolant.

Resumen de: US2020153009A1

A fuel cell arrangement for carrying out a method for ascertaining the overvoltage of a working electrode in a fuel cell, in which the potential of a reference electrode compared to the grounded counter electrode is measured. For the measurement, a fuel cell comprising a polymer electrolyte membrane is used, in which the counter electrode comprises a lateral edge having at least one convexly curved region, and the electrolyte membrane surface, adjoining the counter electrode, comprises an electrode-free region in which the reference electrode is disposed on the electrolyte membrane surface. In contrast, the working electrode is continuous, which is to say has a large surface. The minimum distance Lgap between the reference electrode and the edge of the counter electrode Lgap=3×Ll,r with (a) and (b), where m=ionic conductivity of the electrolyte membrane (Ω−1 cm −1), box=Tafel slope of the half cell for the electrochemical reaction of the working electrode, lm=membrane layer thickness (cm) and jox0=exchange current density of the catalyst of the working electrode per unit of electrode surface in (A cm−2). This arrangement can advantageously be used to ensure that the potential measured at the hydrogen-fed reference electrode corresponds to the overvoltage of the working electrode with sufficient accuracy. The method can be applied to polymer electrolyte membrane fuel cells (PEMFC), to direct methanol fuel cells (DMFC) or to high-temperature fuel cells (SOFC).

Renewable Energy Produced Ammonia, Apparatus, Method and Materials

NºPublicación: US2020148547A1 14/05/2020

Solicitante:

PAPILE CHRISTOPHER [US]

Resumen de: US2020148547A1

The production of NH3, Urea, UAN, and DAP, starting from inherently intermittent renewable energy, such as photovoltaic and wind power, is made economical by use of molten salt thermal energy storage (ESS) and water electrolyzer (WE) concentrated oxygen. The process inputs and equipment apply air; hydrogen-containing fuel, such as biomass; WE (concentrated O2 and H2 producing); thermal ESS equipped with a turbine and generator to steady the electricity input to the WE; and an ammonia plant. The thermal ESS enables minimally sized process equipment including, the WE, the air separation unit and less hydrogen storage. The concentrated oxygen from the water electrolyzer uniquely enables high-temperature thermal ESS input, water and CO2 collection and other fertilizer products, including Urea, UAN and DAP. DAP production is facilitated by using WE high-purity O2 oxidation and ammonium nitrate is similarly facilitated by anhydrous NH3 oxidation.
