Shape Selective Nano-Catalyst for Direct Methanol Fuel Cells (DMFC) Applications
Direct methanol fuel cells (DMFCs) have recently attracted much interest as a promising alternative to conventional batteries, especially in portable electronic devices. DMFCs, however, have several disadvantages including high cost, largely as a result of [...]
Poly(2,5-benzimidazole) Based Polymer Electrolyte Membranes for High Temperature Fuel Cell Applications
In this study, two methods, direct mixing polyhedral oligomeric silsesquioxanos (POSS) with poly(2,5-benzimidazole) (ABPBI) and in-situ synthesis were employed to prepare ABPBI based composite membrane materials, respectively. The morphologies of pristine and composite membranes were [...]
Charge/Discharge Property and Cycle Life of Li4Ti5O12/LiCoO2-LiNi1-x-yCoxAlyO2 Cell for Electricity Storage Applications: Effect of Cell Design Parameters
In this work, Li4Ti5O12 has been used as an anode material in lithium-ion batteries for electricity storage applications, which operate under intermittent cycling conditions with higher charge/discharge rates than 4C (i.e., current extracting the full [...]
A Permselective Layered Silicate Modified by Acid-treatment and Its Use for Blocking of Methanol Crossover in DMFC
Layered silicates currently find uses in ion-exchange, adsorption, catalysis and fabrication of nanocomposites. Several layered silicates have channel systems or open frameworks within layers. They can be used to solve the problem for direct methanol [...]

Activation of Phosphate Olivines LiMPO4 (M = Fe, Mn) by Functionalized Carbon Nanotubes: Application for Cathode Materials of Li-Ion Battery
The nanotube-mediated redox wiring is based on a synergic action of adsorbed redox-active molecule, which provides the interfacial charge transfer to the surface and the single-walled carbon nanotube (SWNT), which transports charge to longer distances [...]
Performance Improvement of Fuel Cell using Platinum Functionalized Aligned Carbon Nanotubes
Proton exchange membrane fuel cells (PEMFCs) are the energy conversion devices with ultrahigh efficiency, zero emission, and high flexibility of the fuel supplies. This study has optimized growth variables of the aligned carbon nanotubes (ACNT) [...]
Identification of Battery Models for Enhanced Battery Management
A large-scale battery system consists of hundreds even thousands battery cells, which have different characteristics even when they are new, and change with time and operating conditions due to aging, operational conditions, and chemical property [...]
Utilization the heat accumulator in large heating system
Cogeneration is currently one of the cheapest ways to generate electricity. The European Union promotes systems for combined heat and power generation. In Europe in general – and Poland in particular – there are numerous [...]
High Performance Solid Polymer Electrolyte Membranes Prepared from Polyether Ether Ketone Composites
High performance solid polymer electrolyte membranes (SPEM) were prepared from polyether ether ketone (PEEK) with high mechanical strength and thermal stability. The sulfonation reaction improved membrane hydrophilicity and water absorbility, and thus increased ionic conductivity [...]
