The characteristics and properties of mixtures of a borosilicate glass and ZrO2 fibres obtained from compacts isothermally sintered are presented. Three different particle sizes of glass powder and different sintering temperatures and times have been used to reveal the influence of the specific surface area and the glass matrix viscosity on sintering. The fundamental developed aspects are the s...

In this study a three-phase homogeneous model was developed to simulate the performance of the molten carbonate fuel cell ~MCFC! cathode. The homogeneous model is based on volume averaging of different variables in the three phases over a small volume element. This approach can be used to model porous electrodes as it represents the real system much better than the conventional agglomerate mode...

Lithium metal is the ideal anode for the next generation of high-energy-density batteries. Nevertheless, dendrite growth, side reactions and infinite relative volume change have prevented it from practical applications. Here, we demonstrate a promising metallic lithium anode design by infusing molten lithium into a polymeric matrix. The electrospun polyimide employed is stable against highly re...

The objective of this work is to study the Li2CO3Na2CO3-K2CO3 (29.5–31.1–39.4 mol%) molten salt and behaviour several metals (Au, Pt, C, Ni W) by electrochemical measurements in under three atmospheres (Ar, CO2 O2/N2). Thermodynamic calculations show that anodic cathodic limits correspond carbonate ions oxidation reduction dioxygen carbon respectively. An internal reference electrode has been d...

A theoretical model for the molten carbonate fuel cell was developed based on the three-phase homogeneous approach. Using this model, the contribution of different cell components to losses in cell performance has been studied. In general, at low current densities, the electrolyte matrix contributed to the major fraction of potential losses. Mass transfer effects became important at high curren...

A deep analysis of the Fuel Cells technologies state of the art has been done in this article. After a general description of the fuel cell base structure the six most important fuel cell technologies Polymeric Electrolyte Membrane Fuel Cells (PEMFC), Direct Methanol Fuel Cells (DMFC), Alkaline Fuel Cells (AFC), Phosphoric Acid Fuel Cell (PAFC), Molten Carbonate Fuel Cell (MCFC), Solid Oxide Fu...
