Investigation of dominant loss mechanisms in low-temperature polymer electrolyte membrane fuel cells.

Beschreibung

This thesis deals with the analysis of dominant loss mechanisms in direct methanol fuel cells (DMFC) and hydrogen fed polymer electrolyte membrane fuel cells (PEFC) by means of experimental characterization and modeling work.
The investigations are focused on the water management in PEFCs and mixed potential formation, catalyst poisoning, methanol-selective cathode catalysts in DMFCs.
