The High Pressure Hydrogen-Oxygen Fuel Cell Ion exchange non-fluorinated membranes were tested in half-cells used as models for hydrogen–oxygen fuel cells. The lower acidity of the membranes allowed... Bacon,T F. - 《Industrial & Engineering Chemistry》 被引量: 36发表: 1960年 加载更多0关于...
The electron-ion interactions were described by the projector augmented wave. Van der Waals interactions were corrected by the DFT-D3 method. A plane-wave basis was set with the cutoff energy of 400 eV. The Brillouin zone was built with a (2 × 2 × 1) Monkhoest-Pack k-...
While the three ensuing sections “Modifying the Electronic Structure”, “Creating Specific Sites for Hydroxide and Hydrogen Adsorption”, and “Altering the Surface of a Catalyst” refer to specific aspects of HER catalysis, the resulting performance of the catalyst will to some degree be a ...
loaded Ru NPs (~5 nm) on the surface of montmorillonite (MMT) by an ion-exchange method with hydrogen reduction, which showed an outstanding H2 release rate up to 29 L min−1 g−1 for the methanolysis of ammonia borane [104]. Such a catalyst showed good durability, as Ru NPs were...
under a constant voltage of 3.0 V. This can be attributed to the improved ion conductivity of H2SO4with elevating the temperature35. In the meantime, the J-V curve shifts upwards with decreasing glass foam thickness at 25 °C. At 3.0 V, the current densities are 17.5 and 37.8...
While fuel cells for other applications have been or are being developed with ionic conduction provided by phosphoric acid, potassium hydroxide, molten carbonates, or solid oxides, automotive applications are focused on ion-exchange polymers in the proton (H+) form consisting of a polyperfluoroethylen...
From 1920 to 1950, the primary method of production was electrolysis. One process involved passing electric current through sulfuric acid to produce the peroxydisulfate ion (S2O8 2-), which was then hydrolyzed to H2O2: 2H2O + S2O82-(aq) 2H2SO4-(aq) + H2O2(aq).the relatively high cost ...
the dissociation of water, and an ion exchange membrane separating the electrodes causes the hydrogen and oxygen molecules to be released separately. The alkaline electrolyzer may be less expensive but handling of the caustic electrolyte solutions during maintenance operations may be a deterrent to some...
Apart from that the stability of the catalyst is also very high due to the formation of Cu(I) ion on the surface of TiO2 after solar irradiation which also plays a crucial role in solar harvesting [95]. Advancement came in the area of RGO research towards photocatalytic application when it...
