Generating large force/displacement actuators at the millimeter and sub-millimeter scales remains an important challenge for microsystems engineers. One promising solution is to integrate high-energy density solid propellant fuels in microsystems (pyroMEMS ...
This study investigates the performance of a standard Ni-YSZ anode supported cell under ethanol steam reforming operating conditions. Therefore, the fuel cell was directly operated with a steam/ethanol mixture (3 to 1 molar). Other gas mixtures were also u ...
Sphere-pac fuel, together with Vipac fuel, is one of the most elaborate particle fuel concepts. In Chapter 00059, Sphere-pac and VIPAC, the Sphere-pac and Vipac concepts are discussed from a more general perspective, explaining the motivation, the producti ...
Even though rail transportation is one of the most fuel efficient forms of surface transportation, fueling costs are the single highest operating cost head for railroad companies. For larger companies with several thousands of miles of rail network, the fu ...
This project involved the conversion of a British Waterways maintenance craft to a canal boat, powered by a combination of a solid-state hydrogen store, Proton Exchange Membrane (PEM) fuel cell, lead-acid battery pack and a high-efficiency, permanent magne ...
Even though rail transportation is one of the most fuel efficient forms of surface transportation, fueling costs are one of the highest operating cost head for railroad companies. In US, unlike Europe, fueling costs are indeed, by far, the single highest o ...
Recently, the development of micro-scale solid oxide fuel cells (µ-SOFCs) has become a promising research topic in the area of portable energy production. A µ-SOFC system, which can provide 1 to 2 W electrical power under an operating temperature of 550°C ...
It is now common knowledge that flow uniformity within repeat-elements - as well as among them in stack configuration - is of major importance for the performance and reliability of solid oxide fuel cells (SOFCs). At first, a design optimization of the con ...
Abstract: Solid oxide fuel cells are able to convert fuels, including hydrocarbons, to electricity with an unbeatable efficiency even for small systems. One of the main limitations for long-term utilization is the reduction-oxidation cycling (RedOx cycles) ...
In this paper an investigation on the performance of a commercial Proton Exchange Membrane (PEM) fuel cell, installed at the laboratory of the University of Bologna, is carried out, taking into account the anodic exhaust management and its effects on the f ...
