TECHNOLOGY REPORT
down and then we've dropped in the hydrogen
fuel-cell unit and balancer plant
around that package, just above where
the battery currently is, where the battery
would be in the EVR-H. "
This arrangement was chosen because
it was the easiest place to accommodate
it on this platform. The engineering
team also considered packaging
a fuel cell at the front of the vehicle,
but found that they could not package
enough capacity for the required power
output. Accommodating the fuel-cell
system at the rear also leaves space for
a front drive motor for an all-wheeldrive
variant.
" What we've done currently with the
initial study on the hydrogen variant is
that we've modelled it around a rearwheel-drive-only
variant and then we've
packaged an additional hydrogen tank in
the front, where on the other fourwheel-drive
variants you would have a
front EDU (electric drive unit), " Dew
The EVR platform
currently is equipped
with twin-motor rear
drive, but a variant with
a single front-drive
motor also envisaged.
said., " So from a hydrogen tank point of
view, we essentially package one tank at
the front and two at the rear. "
While it is possible to get up to 200

to 250 kW by stacking fuel cells together,
there wasn't enough space to do
that with the EVR platform; WAE opted
for a 118-kW fuel cell stack, with an additional
400-450 kW coming from the
battery electric drive system.
This should enable range to be extended
to 500 to 600 km (310 to 373 miles).
WAE expects the fuel-cell variant to reach
the test rig stage by June 2023 and the
end of 2023 before a prototype is ready.
