PEM Fuel Cell
Range Extender System
for Battery Electric vehicles
Motivation
Project goals
Methodology
In order to increase the
attractiveness of battery electric
vehicles the battery costs must be
reduced and the driving range
increased. Both requirements can
be achieved via a range extender
concept. The range extender can
decrease the battery capacity
requirement, and subsequently
the battery cost, while increasing
the vehicle range. Within the PEM
REX S project it is planned to
develop a competitive PEM Fuel
Cell range extender system.
A significant focus of the project is
the development of an optimized
operating procedure for the PEM
fuel cell range extender system
and the establishment of a
“Diagnosis based- Control” feature
that provides an early warning in
order to protect the stack from
damage
development.
The
Integration of the developed
system into a demonstration
vehicle will be achieved following a
vehicle integration study.
Development of a PEMFC range
extender system concept with
attention to the Business case
sense and cost, available vehicle
space
and
the
vehicle
performance.
Within work package 1 the system
specification will be defined based
on vehicle simulation. Within work
package 2, PEM stacks from the
automotive component supplier
ElringKlinger will be accordingly
optimized and delivered. Within
work package 3, a laboratory
based PEM range extender
prototype
system
will
be
constructed and developed. In
work package 4, all relevant
damage modes will be identified
and these modes will be
implemented into the “diagnostics
based control” operating strategy.
In work package 5 all the tests are
focused on HiL load profile tests on
the lab based PEM range extender
prototype. Finally, in work package
6 a vehicle integration study for
the PEM range extender system
will be completed.
