State estimation in fuel cell systems : a sliding mode approach
Luna Pacho, Julio Alberto; Usai, Elio; Husar, Attila Peter; Serra, Maria (2015)
Text en actes de congrés
Accés obertIn this paper, a nonlinear distributed parameter observer (NDOP) is developed for the estimation of the internal condi-tions of a proton exchange membrane fuel cell (PEMFC). In particular, the estimation of the internal ... -
State machine-based architecture to control system processes in a hybrid fuel cell electric vehicle
Molavi, Ali; Husar, Attila Peter; Hjortberg, Hampus; Nilsson, Niclas; Kogler, Markus; Monreal, Juan Sanchez; Eldigair, Yousif; Serra, Maria (Elsevier, 2023-07-20)
Article
Accés obertThis paper presents the development and implementation of a system supervisory controller in a hydrogen-based fuel cell electric vehicle. The controller's primary function is to ensure the safe control of the fuel cell ... -
State observers design for PEMFC systems
Luna Pacho, Julio Alberto; Husar, Attila Peter; Serra, Maria (2014)
Text en actes de congrés
Accés restringit per política de l'editorialThis work presents the development of a nonlinear state observer to estimate the values of the different gas species concentration profiles in a Proton Exchange Membrane Fuel Cell (PEMFC) energy system. The selection of ... -
Study of hydrogen purge effects on performance and efficiency of a PEM fuel cell system
Strahl, Stephan; Husar, Attila Peter; Riera, Jordi (Riera Colomer) (2012)
Text en actes de congrés
Accés obertExperimental analysis and CFD modeling is used in this work to analyze system efficiency related to hydrogen purge based water management in an open-cathode PEM fuel cell system. Excess water in a deadended anode decreases ... -
Water transport study in high temperature fuel cell stack
Bezmalinovic, Dario; Husar, Attila Peter (2012)
Text en actes de congrés
Accés obertThis work presents analysis of water transport phenomena in the 120 Wel high temperature PEM fuel cell stack. Phosphoric acid doped PBI membranes are known for their abilities to work with dry gases; however water in the ... -
Water transport study in high temperature proton exchange membrane fuel cell stack
Bezmalinovic, Dario; Strahl, Stephan; Roda Serrat, Vicente; Husar, Attila Peter (2014)
Article
Accés obertA study of water transport in a high temperature phosphoric acid doped polybenzimidazole (PBI) membrane fuel cell stack is reported. Tests with different stoichiometries of dry cathode and different humidity levels of anode ...
