Air-breathing versus conventional polymer electrolyte fuel cells: A parametric numerical study
(Elsevier, 2022)
Two mathematical models have been built for air-breathing and conventional polymer electrolyte fuel cells to explore the reasons affecting the cell performance. A parametric study has been conducted to (i) investigate how ...
Dynamic models for air-breathing and conventional polymer electrolyte fuel cells: A comparative study
(Elsevier, 2022)
Two dynamic models have been built for air-breathing and conventional polymer electrolyte fuel cells (PEFCs) in order to comparatively investigate the impacts of some key parameters on the transient response to load ...
A numerical method for solving a class of systems of nonlinear Pantograph differential equations
(Elsevier, 2022)
In this paper, Fibonacci collocation method is firstly used for approximately solving a class of systems of nonlinear Pantograph differential equations with initial conditions. The problem is firstly reduced into a nonlinear ...
Industrial scale extrusion performance of cryogenically processed DIN 100 Cr6 and DIN 21NiCrMo2 steels
(CSIC Consejo Superior de Investigaciones Cientificas, 2022)
The effects of diferent heat and cryogenic (sub-zero) treatment parameters such as temperature and holding time on the microstructure (amount of retained austenite) and hardness of extrusion molds produced from the 21NiCrMo2 ...
Key properties of inorganic thermoelectric materials-tables (version 1)
(IOP Publishing Ltd, 2022)
