Rather than go all-out on the technology, this EV has been conceived with reusable components – and the circular economy – in mind. Rory Jackson reports. End-to-end sustainability is a troublesome target for EV engineers to track. Reducing vehicle emissions at the point of use is easy enough, but reducing the emissions...

Fuel cells

Nick Flaherty explains the issues at play when designing and building a fuel cell. Sometimes it seems that the specification and design of a fuel cell is more of an art than a matter of engineering. While the basics of the cells are clear, most often based around a stack of proton exchange membrane (PEM) cells...

How Clean are EVs

There’s no doubt that EVs are much cleaner and friendlier to be around than anything powered by an internal combustion engine, as they produce no local emissions (writes Peter Donaldson). They also use energy more efficiently in stop-go traffic, particularly when fitted with regenerative braking systems. Even petrol-diesel electric hybrids allow the engine to be...

Volume plan for hydrogen cells

In a key move for hydrogen-powered electric technology, Bosch is starting volume production of fuel cell systems for electric vehicles using technology from Powercell (writes Nick Flaherty). The two companies will jointly develop polymer-electrolyte membrane stacks for fuel cells that convert hydrogen to electricity, and Bosch will make the stacks under licence in 2022. Bosch, a...

Hydrogen fuel cells

There is something of an ongoing debate in the world of e-mobility as to hydrogen’s place in the energy ecosystem (writes Lawrence Butcher). While manufacturers such as Toyota are throwing their weight behind the fuel, and actively marketing fuel cell electric vehicles (FCEVs), others such as...

Hydrogen

Nick Flaherty highlights some of the inroads developers are making into rolling out a range of hydrogen-powered vehicles. Many of the engineering challenges with converting hydrogen to electricity to drive a motor in a vehicle have been addressed over the past decade through the development...
