    • Decarbonization potential of fuel cell technologies in micro-cogeneration applications: spotlight on SOFCs in a Belgian case studyPeer reviewedClosed access 

      30 janvier 2025, Nicolas Paulus, HE de la Province de Liège
      Article scientifique
      There is a plethora of fuel cell technologies, many of which hold great promise in terms of their decarbonisation potential, which this paper aims to explore. In fact, this paper is primarily based on the only two existing technologies on the market, polymer exchange membrane fuel cells and solid oxide fuel cells (SOFCs). Unfortunately, these commercial systems mainly use natural gas as primary fuel ...

    • Experimental investigation and modelling of a Solid Oxide Fuel Cell (SOFC) used in residential cogeneration applicationsPeer reviewedOpen access 

      18 septembre 2024, Paulus, Nicolas; Lemort, Vincent, HE de la Province de Liège
      Article scientifique
      The 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 boilerPeer reviewedOpen access 

      10 septembre 2023, Vincent Lemort; Paulus, Nicolas, HE de la Province de Liège
      Article scientifique
      The 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 systemsPeer reviewedOpen access 

      15 mai 2022, Paulus, Nicolas; Lemort, Vincent, HE de la Province de Liège
      Acte de conférence ou de colloque
      Much 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 ...
