The disintegration of the carbon anodes during the electrolysis of alumina produces dust particles contaminating the electrolytic bath. This phenomenon, called dusting, is one of the most deleterious Al electrolysis failures, as it leads to a significant d ...
Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
A simple technique for microstructuring ceramic thin films by micromachining substrates using standard photolithographic techniques was investigated. The ceramic perovskite is used to illustrate the method because of its importance for the fabrication of e ...
The temperature profile generated by a thermo-electro-chemical model was used to calculate the thermal stress distribution in a tubular solid oxide fuel cell (SOFC). The solid heat balances were calculated separately for each layer of the MEA (membrane ele ...
Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. Best results are typically achieved using model based control strategies. This paper elaborates a control oriented PEM fuel cel ...
We report the detection of protein molecules with nanofabricated pores using the resistive pulse sensing method. A 20-nm -thick silicon nitride membrane with a nanofabricated pore measuring about 55 nm in diameter separated an electrolyte cell into two com ...
When running a fuel cell system in load following mode, several operating points (i.e. a combination of gas flow rates, pressures, humidities, temperatures and current density) can provide the required net power. Typically, only one of those operating poin ...
A solid oxide fuel cell structure obtainable by selective electrochemical processing, comprising an electrolyte membrane (4) formed by a thin film more than 50nm but less than l0[mu]m thick, covering a supporting structure (1) made of a bulk substrate, the ...
Electrical output behaviour obtained on solid oxide fuel cell stacks, based on planar anode supported cells (50 or 100 cm2 active area) and metallic interconnects, is reported. Stacks (1–12 cells) have been operated with cathode air and anode hydrogen flow ...
Proton exchange membrane (PEM) fuel cells show characteristics of high power density, low operating temperature, and fast start-up capability, which make them potentially suitable to replace conventional power sources (e.g., internal combustion engines) as ...
