F-Cell roadshow hits number three

Having Europe and North America, the F-Cell roadshow is now in Australia the green-painted B-Class F-CELL are making the long trek Sydney to Perth. Surrounding the fleet is an entourage of more a dozen vehicles including Sprinter vans set up as mobile and refuel stations and a semi-trailer with striking red full-length of hydrogen.

Benz wants the World Drive, a four global circumnavigation taking 14 four continents and a wide of climatic and driving conditions, to several points. In preparation for its of fuel cell powertrains its mainstream fleet in 2015, it to give buyers and legislators of time to get used to what is to a mysterious new technology. It wants to its maturity and its readiness for everyday use, and it wants to demonstrate its over other electric long range, short times, potential cost-effectiveness and emissions. All that and they’ve it the feel (if not the sound) of a conventional combustion engined car.

The F Cell uses the fuel not as a direct source of power for the but as an on-board charger for its lithium-ion – as a range extender, similar to the way Volt uses its petrol

Fuel cell-charged EVs offer a of major advantages over grid-charged counterparts in the form of range and shorter refuel They also have a of downsides. Firstly, they’re energy efficient, with the car to carry a two-phase energy system to stay mobile.

Then there’s the matter of infrastructure, of which there’s none at the moment. Benz is running experimental fleets of F on the roads in Europe and the US. Germany has all of 30 fueling stations, of which seven are public-access. The US has limited – very limited numbers – in New Los Angeles and Michigan.

The primary a hydrogen-sourced top-up offers a conventional PHEV like the presents at the exhaust outlet. It off nothing but steam. Measured Daimler and Linde – the global gases giant providing refueling facilities for the World fleet – estimate hydrogen in this form generates a gas footprint about 30 per cent than diesel. The only emissions lie in the primary energy used in extracting the hydrogen. a clean, renewable way to extract it – are solar technologies showing promise here – and it’s zero emissions, well to

Fuel consumption is measured in of hydrogen per 100 kilometers. Benz the F Cell uses less 1kg/100km. That equates about 3.3L/100km of diesel. with due – but not obsessive – care, the says a 4kg tank of hydrogen is for a range of about 400km in environments, where the car is able to best use of it energy regeneration during deceleration and braking.

Over the course of that 4kg the fuel cell will off enough water vapor to into about 36 liters of (which leaves one wondering if a full of fuel cell might not live in something to a permanent La Nina event).

costs? At the moment it costs 8-9 to fill a 4kg tank. With the economies of scale inevitable the F Cell’s mainstream release in the company’s advice is that drop to $2-3.

How a Fuel Works

The principle of the fuel cell is described as being the reverse of electrolysis. Essentially a controlled reaction between hydrogen and in the air, it uses takes within a simple cell two electrodes (a cathode and an anode) by an electrolyte.

The process begins hydrogen is fed into the anode of the fuel cell, where molecule is separated in the presence of the into an electron and a hydrogen

The negatively charged electrons to the cathode through the electric reacting with the oxygen.

the positively charged protons toward the cathode through a membrane, the electrons can’t. instead have to take the external way through the cathode. transfer of electrons is expressed as energy, which the unit into the Li-ion battery, it charged.

Since the only by-products that charge are water and the unit produces no local
