EP3128215B1 - Fluid valve
08 février 2017, HE de la Province de LiègeBrevetHydraulic valves often require actuators or servo motors with dedicated electronics and dedicated electrical power supply. So, you have usually "2 signals" to provide to the actuator/motor : the command signal, which is usually low voltage and/or low current (no real power with it) and the power supply. The actuator/motor requires electronics to handle both signals (and that is expensive, and in ... -

Experimental assessment of pollutant emissions from residential fuel cells and comparative benchmark analysis
07 mai 2024, HE de la Province de LiègeArticle scientifiqueEnergy transition currently brings focus on fuel cell micro-combined heat and power (mCHP) systems for residential uses. The two main technologies already commercialized are the Proton Exchange Membrane Fuel Cells (PEMFCs) and Solid Oxide Fuel Cells (SOFCs). The pollutant emissions of one system of each technology have been tested with a portable probe both in laboratory and field-test configurations. ... -
Experimental investigation and modelling of a Solid Oxide Fuel Cell (SOFC) used in residential cogeneration applications
18 septembre 2024, HE de la Province de LiègeArticle scientifiqueThe much-needed energy transition brings special focus on fuel cell micro-combined Heat and Power (mCHP or micro-CHP) systems for residential uses, one of which is a Solid Oxide Fuel Cell (SOFC), fed by natural gas, designed to provide continuously 1.5 kWel with an associated amazingly high expected Low heating Value (LHV) electrical efficiency of 60%. This power output can be modulated as desired ... -

Field-test performance models of a residential micro-cogeneration system based on the hybridization of a proton exchange membrane fuel cell and a gas condensing boiler
10 septembre 2023, HE de la Province de LiègeArticle scientifiqueThe energy transition brings focus on cogeneration systems, even at residential levels. One of the latter systems consists in a proton exchange membrane fuel cell (PEMFC) combined with a gas condensing boiler and a 220L domestic hot water tank. The system, fed by natural gas, is designed to provide the heat demands of residential houses and to participate locally in the electrical produc-tion thanks ... -

Grid-impact factors of field-tested residential Proton Exchange Membrane Fuel Cell systems
15 mai 2022, HE de la Province de LiègeActe de conférence ou de colloqueMuch needed energy transition currently brings focus on micro-combined heat and power (mCHP) systems for residential uses, especially on low-capacity fuel cells (about 1 kWel) because it has been reported that they allow for increased CO2 savings per kWel compared to engine-based mCHP’s [1]. One of those (already commercialized), is a Proton Exchange Membrane Fuel Cell (PEMFC) system hybridized with ... -
