Hydrogen and fuel cells are well suited to a range of mobility and vehicle challenges. A fuel cell electric vehicle (FCEV) is very similar to an electric vehicle, except with the greater volumetric energy density than a batteries, hydrogen offers much greater range more than 300-400 miles in the leading cars, such as those just entering the market from Hyundai and Toyota.

This increased range for weight and volume advantage means that a good use of hydrogen and fuel cell systems is to extend the range of any electric vehicle, or mobile device, effectively acting as a mobile battery charger. This is a good example of fuel cells working with other technologies in hybrid systems,

Arcola Energy has developed our AutoPAK system, a complete power unit including hydrogen supply, fuel cell, control systems and power electronics, using air cooled fuel cells. These systems can be “single stack” providing 3-5 kW or dual stack providing 6-10 kW.

AutoPAK is a demonstration of system integration into automotive power trains which we have carried out for lightweight vehicle developers Riversimple and Microcab in the UK and a number of international customers. The knowledge gained means the team can be a valuable partner in the development of integrated fuel cell power trains for a wide range of mobility applications.



Coventry-based SME Microcab has developed the H2EV, a prototype lightweight city car as a model for future mobility. Measuring just 3.5 metres in length, the Microcab H2EV has a Lotus-engineered bonded-aluminium chassis, weighing just 60kg, and allowing for both passenger car and commercial vehicle body-styles.

Arcola Energy has integrated air-cooled fuel cells using our complete AutoPAK system, including hydrogen cylinder and delivery system, fuel cell, power and control electronics, ECU, and remote monitoring system. The H2EV has a range of up to 180 miles on a single 1.8kg tank of hydrogen, which can be filled in just three minutes.




Arcola Energy has been working with Riversimple for several years, supporting the development of their revolutionary ultra-efficient vehicle. We have integrated a dual fuel cell system into Riversimple’s power electronics and power train, providing fuel cell system control and interface into the vehicle management system.
