J. Fuel Cell Sci. Technol 4(4), 516-519 (Apr 26, 2006) (4 pages) doi:10.1115/1.2757187 History: Received November 30, 2005; Revised April 26, 2006

The paper focuses on the experimental results of a series of tests performed on a hybrid electrical source. The hybrid generator is made up of a fuel cell primary source equipped with an ultracapacitor storage device. The paper presents an examination of the steady-state and transient performance of the hybrid fuel cell-ultracapacitor source in terms of power quality. The aim is to investigate on fuel cell-ultracapacitor source’s behavior to feed pulsing loads.
