Getting Over the Hump: How Dynamic Beam Lasers Could Be the Breakthrough for Manufacturing Fuel Cell Cars

Responding to auto industry demand, Civan Lasers, Fraunhofer ILT, and Smart
Move to increase bipolar welding feed rate

Dynamic beam lasers may provide the automotive industry with a technological
solution for economically mass-producing clean energy engines through an
increased feed rate for bipolar welding, according to recent findings from
the Eureka Project, based at Fraunhofer Labs in Aachen, Germany.

As the automotive industry shifts to e-mobility, manufacturers are also
shifting from combustion engines to fuel cell engines. The challenge to
efficiently produce fuel cells lies in welding the bipolar plates – thin
plates of just hundreds of microns. Each cell contains 300 to 400 plates
with a weld seam of 3 to 6 meters. While there are many efforts to increase
welding speed to keep up with demand, increasing the feed rate to more than
0.5 m/sec results in welding defects, leading to faulty parts and a backlog
of materials.

The three companies driving the Eureka Project – Civan Lasers in Israel, the
Fraunhofer Institute for Laser Technology in Germany, and Smart Move in
Germany – are international leaders in the field of laser welding. They aim
to solve the welding problem by implementing Civan Lasers’ dynamic beam
laser technology, which can wobble the beam in MHz frequencies, creating a
faster, more accurate weld of the bipolar plates.

In response to these findings, Dr. Eyal Shekel, Civan’s CEO, shared, “We are
confident that the unique capabilities of the dynamic beam laser will be
able to solve this challenge.”

Dr. Alexander Olowinsky, a researcher with Fraunhofer ILT, added, “We look
to reach a breakthrough in this project by using advanced sensors and
complex beam shapes in high frequencies that were not available in the
past.”

As testing continues, it is becoming clear that dynamic beam lasers could be
the game-changing solution for fuel cell engine manufacturers.
