This paper presents an experimental study of the impact of toluene on the performance of anode-supported (AS) Ni/YSZ SOFC operating at ∼800 °C, 0.25 A/cm2 fed with H2 and biosyngas. Toluene was added to the fuel stream and its concentration increased from ...
The Hall Effect sensors are one of the most commonly used sensing technologies today. They are employed in many applications for direct magnetic field sensing and serve a multitude of low power applications within automotive and industrial electronics as c ...
Nd1.95NiO4+delta (NNO) cathode supported microtubular cells were fabricated and characterized. This material presents superior oxygen transport properties in comparison with other commonly used cathode materials. The supporting tubes were fabricated by col ...
Ce document décrit l'utilisation des thermistances NTC & PTC (y compris platine) pour la mesure en température. This document describes the use of NTC & PTC (platinum-type RTDs included) resistors for temperature measurements. ...
The increasing demand for highly precise, yet compact and low power timing devices pushes the research in the field of chip scale atomic clocks (CSACs). At the heart of a CSAC, there is a vapor cell containing a few micrograms of alkali metal, such as rubi ...
Pure gallium and pure boron (PureGaB) Ge-on-Si photodiodes were fabricated in a CMOS compatible process and operated in linear and avalanche mode. Three different pixel geometries with very different area-to-perimeter ratios were investigated in linear arr ...
During their lifetime, glass panels are repetitively exposed to thermal stresses. These thermal stresses result from temperature differences within the panel, which most notably cause the edges of the panels to be stressed in tension. When these thermal st ...
Cost-effective production of solar fuels requires robust and earth-abundant oxygen evolution reaction (OER) catalysts. Herein, we report that ultrathin nanoplates of cobaltmanganese layered double hydroxide (CoMn LDH) are a highly active and stable oxygen ...
In this paper the effect of systematic errors in gas temperature measurements on the thermal control of a Solid Oxide Fuel Cell system is demonstrated. Three control schemes were tested under two different conditions. First, the real gas temperature at the ...
Lifetime and durability issues connected with Solid Oxide Fuel Cell (SOFC) technology are strongly related to the amount of contaminants that reach the stack. In this study the focus is on organic silicon compounds (siloxanes) and their highly detrimental ...
