‘Battery vs Fuel Cells’
When we say ‘electric vehicle’ the electric the refers to the motor and propulsion system.
How we deliver electrons to the electric motor remains a contentious debate on Twitter and inside auto industry board rooms. The debate is usually ‘battery’ vs ‘fuel cell’ as the source of power.
On the sideline of the debate, are policy-makers and consumers who seem confused by short-term conviction of battery advocates versus a newly empowered group of fuel cell advocates.
Daimler’s View: Integration is the Strategy
Daimler is taking the high road in this debate – and showing us all that the answer might be ‘battery plus fuel cell’.
In addition to battery-powered EVs, the company continues to promote fuel cells as part of its Electric Vehicle portfolio. The push for integration under its EQ Power mantra includes the pre-series model GLC F-CELL.
The GLC F-Cell includes a lithium ion battery and a fuel cell fed by 4.4 kg of hydrogen on giving it a range of up to 437 kilometres. The engineering leverages the strengths of batteries and fuel cells and their related performance characteristics in everything from propulsion to capturing regenerative power from braking to capturing waste heat for interior.
In a recent promotional page Daimler states unequivocally that:
The potential of fuel cell technology, and of hydrogen for energy storage, is beyond question.
“We’ll keep the fuel-cell technology in development so that we have this technology option should there be a shift in the market,” said Ola Kaellenius, head of development at Daimler AG, which is about to market its GLC F-Cell sport utility vehicle that can drive 500 kilometers on a single tank.
While energy bloggers claim ‘Daimler has given up on fuel cells’, the company has come out strongly in favor of integration of fuel cell and battery technologies as the key to electric propulsion:
Fuel cell technology is an integral part of our powertrain strategy.The advantages are very clear to us: zero emissions, long ranges and short tanking times, plus a wide range of applications from cars to buses, other large commercial vehicles and not least also for stationary applications.
