Abstract [en]

A range extender in a battery electric vehicle supplements the existing drive system as an add-on module. Range extenders can comprise of any combination of conventional fuel, battery or fuel cell driven modules. The idea of a sub-system changes with the type of range extender. In this work, hydrogen generation is studied, a fuel is used to power the range extender via a fuel cell.The thesis presents the work in progress for development of the sub-system for a range extender based on on-board production of hydrogen for automobiles. Several aspects of chemistry play equally pivotal role in control, hassle-free operation and safety of the system. Aftertreatment of the fuel by-products is the notorious issue that limits the reusing the reactor effecting the range extender. Along with this, reducing the reaction time with minimal usage of fuel is investigated. Both of these pressing issues are resolved correspondingly to an extent with the addition of several chemicals. In addition, with the help of characterization techniques, a robust circular economy outlook of the range extender system has been initiated.

Abstract [sv]

En distansförlängare i ett eldrivet fordon kompletterar det befintliga drivsystemet som en tilläggsmodul. Distansförlängaren kan vara olika kombinationer av konventionella bränsle-, batteri- och bränslecelldrivna moduler. Utformningen av de övriga delarna av undersystemet beror på vilken distansförlängare som används.

I detta arbete drivs distansförlängaren av en bränslecell, bränslet till bränslecellen genereras i distansförlängaren. Avhandlingen presenterar det pågående arbetet för utvecklingen av undersystemet hos en distansförlängare. Undersystemet baseras på ombordsproduktion av väte för bilar. Flera aspekter av kemi spelar en lika viktig roll i kontroll, problemfri drift och säkerhet. Efterbehandling av bränslets biprodukter är det ständiga problemet som begränsar reaktorns återanvändbarhet vilket påverkar distansförlängaren. Tillsammans med detta undersöks minskning av reaktionstiden med minimal användning av bränsle. Båda dessa pressande problem löses i en utsträckning med tillsatsen av flera kemikalier. Dessutom har en robust cirkulärekonomisk syn på distansförlängaren utvecklats med hjälp av olika karakteriseringstekniker.
