Thermodynamic Effects of Nanotechnological Augmentation of Hydrogen Fuel Cells

“…Enthalpy is the thermodynamic quantity that states the total heat content of the system, which is the sum of all internal process in a closed system 9 . For homogeneous systems, enthalpy is solely based on the size of the system as it is an extensive property 10 . This is shown in equation [5], where enthalpy (H) is the sum of the internal energy of the system (U) and the product of pressure (P) and volume (V) of the system 9 .…”

“…This is then equal sum of Eᶱcell, which is the standard cell potential, or the potential of the chemical reaction that takes place in the cell, which varies depending on the entropy in the reaction 10 . Once the ideal potential of the system has been determined for standard conditions the ideal voltage can then be determined for other temperature and pressure through the use of the Nernst equation.…”

Innovation in Russian District Heating: Opportunities, Barriers, Mechanisms

“…Russian district heating systems are less efficient technologically and economically than their best foreign counterparts. For this reason, local small-capacity heating sources based on highly efficient cogeneration plants seem entirely commercially viable as innovative solutions [Pehnt et al, 2006;Parker, 2009;Pilatowsky et al, 2011;Praetorius et al, 2012]. However, artificial administrative prohibitions must be revoked for them to spread.…”

Comparison of Analytical and Numerical Models of Adsorber/desorber of Silica Gel-water Adsorption Heat Pump

“…In [14,15] the possibilities and limits of this technology are analysed. Solid-gas sorption heat powered cycles appear to be an attractive alternative for cooling [16] or air conditioning applications [17]. Cogeneration of fuel cell and sorption air conditioning systems was widely analysed in [18].…”
