abstract = {This paper describes the energy storage characterization
for a direct methanol fuel cell (DMFC) hybrid system for
light traction applications. In a first step, the DMFC stack
and the energy storage were dimensioned. To dimension the
energy storage, the required energy density and power
density were calculated. These are influenced by the
operating states of the vehicle as well as the highly
fluctuating load profile. For this kind of application a
high energy density as well as a high power density is
needed. Therefore, super capacitors are not the energy
storage of choice. As an alternative, suitable batteries
were analyzed in terms of their behavior in the DMFC hybrid
system. Therefore, a characterization procedure was
developed consisting of five different tests. These tests
were developed adapted to the requirements of the
application. They help to characterize the battery in terms
of energy content, high power capability during charge and
discharge, thermal behavior and lifetime. The tests showed
that all batteries have to be operated on a partial state of
charge (pSOC) and a thermal management is very important.
Especially lead-acid battery show an decrease in lifetime
under a pSOC operation. Therefore, a lithium battery was
identified as the suitable energy storage for the considered
application. (C) 2010 Elsevier B.V. All rights reserved.},
