Solid Oxide Fuel Cells (SOFC) are an emerging technology among different fuel cell types since they are successfully used in stationary cogeneration units to produce heat and electricity. Different scale applications are proposed as alternative energy sources for residential usage and industrial power plants, reducing the greenhouse gas...

High-temperature fuel cells are a promising technology due to their high energy efficiency and low environmental impacts compared to conventional engines. Nevertheless, they have a limited lifetime which reduces the use to a few application fields. Among them, Solid Oxide Fuel Cells (SOFCs) have had a recent development at the industrial level...

Filled skutterudites form a wide class of intermetallic compounds thoroughly studied for their promising thermoelectric performance. An electrochemical study was performed on a set of two samples of filled skutterudite with composition Sm0.1(Fe0.45Ni0.55)4Sb12 differing for the content of additional phases. The aim of the study is to test their...

The structural and thermoelectric properties of the filled skutterudite (Sm,Gd)y(FexNi1-x)4 Sb12 were investigated and critically compared to the ones in the Sm-containing system with the aim of unravelling the effect of double filling on filling fraction and thermal conductivity. Several samples (x = 0.50-0.90 and y = 0.15-0.48) were prepared...

In this work, a photospectrometric method was used to quantify chromium evaporation from the AISI 441 ferritic stainless steel. Experiments were conducted for 250 h in the temperature range of 650–850 °C to evaluate the time and temperature dependence of chromium evaporation in the initial oxidation stage. The results showed a thermally...

Two commercial ferritic stainless steels (FSSs), referred to as Steel A and Steel B, designed for specific high-temperature applications, were tested in static air for 2000 h at 750 °C to evaluate their potential as base materials for interconnects (ICs) in Intermediate Temperature Solid Oxide Fuel Cell stacks (IT-SOFCs). Their oxidation...

The aim of this work was to develop polylactic acid (PLA) based porous films with suitable properties to be used as sensors and absorbers. The formulation was designed to make the films porous, ductile, and conductive and characterized by surface functionalization. The phase inversion method was used to impart porosity to the polymer film....

We present a two-step surface modification process to tailor the micro and nano morphology of niobium oxide layers. Niobium was firstly anodized in spark regime in a Ca-and P-containing solution and subsequently treated by acid etching. The effects of anodizing time and applied potential on the surface morphology is investigated with SEM and...
