| Abstract |
This paper deals with a realization, experimental validation and test results of an electronic active load
for a 5 kW PEMFC generator. The active load is a part of the French interlab “SPACT” project which
aim is to use a testing bench in order to carry out experimental tests on Fuel Cell for transportation
applications. The active load should reproduce the constraints of an energy conversion chain for
transportation application supplied by a Fuel Cell generator. These constraints are of both types: the
first one are load current variations constraints linked to the road or railway mission profiles, the
second one are constraints due to the power electronic interface between the Fuel Cell generator and
the load. Particularly, we will focus on both amplitude and frequency of the pulsed current generated
by the static converters and their influence on the Fuel Cell stack. Moreover, we will consider security
and short-circuit protection measures as fundamental realization criteria for the power electronics
components of the active load. The electronic control part of the active load has been realized by the
GREEN laboratory of Nancy, also partner of the “SPACT” project. Several test results for the active
load have been done at the INRETS LTN lab, then the active load has been tested and its working
validated on the 5 kW Fuel Cell test bench at the L2ES laboratory in Belfort. |
