Cyclic voltammetry of LiCr0.15Mn1.85O4 in an aqueous LiNO3 solution
(Journal of Power Sources, 2007)
Cyclic voltammetry (CV) of LiCr0.15Mn1.85O4, synthesized by rapid glycine-nitrate method (GNM), was performed in a saturated aqueous LiNO3 (similar to 9 M) solution. At rather high polarization rate of 10 mV s(-1) two well ...
Comparison of different electrode materials - Energy requirements in the electrolytic hydrogen evolution process
(Journal of Power Sources, 2006)
Hydrogen is one of the most widely produced commodities in the world economy. The basic technologies for producing hydrogen via the electrolysis of water have long been known. However, there are disadvantages when using ...
Ionic activators in the electrolytic production of hydrogen - cost reduction-analysis of the cathode
(Journal of Power Sources, 2004)
As recent technology progress makes hydrogen a realistic long-term energy option with little or no pollution, development of new methods for its production and improvement of conventional technology is important. In spite ...
Hydrogen generation from water electrolysis - possibilities of energy saving
(Journal of Power Sources, 2003)
Hydrogen production via electrolysis of water from alkaline aqueous electrolytes is a well-established conventional technology. However, due to high energy requirements of about 4.5-5 kWh/m(n)(3) H-2 in most industrial ...
Pt/C doped by MoOx as the electrocatalyst for oxygen reduction and methanol oxidation
(Journal of Power Sources, 2008)
The oxidation of methanol and reduction of oxygen were studied on MoOx-Pt/C nano-catalysts prepared by the polyole method combined by MoOx post-deposition. The catalysts were characterized by TEM and EDX. The presented ...
Self-propagating room temperature synthesis of nanopowders for solid oxide fuel cells (SOFC)
(Journal of Power Sources, 2005)
Ceria based solid solutions are promising ceramic electrolytes for SOFC which will be able to function at intermediate temperatures. In accordance with common trends to decrease the production and operating costs of new ...
Improved energy efficiency of the electrolytic evolution of hydrogen - Comparison of conventional and advanced electrode materials
(Journal of Power Sources, 2005)
With the idea to improve the efficiency of the electrolytic production of hydrogen by electrolysis, from water KOH solutions, the intermetallic Hf2Co was investigated as cathode. This cathode was used single or in combination ...
