Is A Small Hydrogen Fuel Cell Car Possible?
By small car, I’m meaning something like a Ford Fiesta or a Vauxhall Astra.
Consider.
- The car will have a power unit of about 100 KW.
- With four passengers the car would probably weigh about 1500 Kg.
Does A 100 KW Fuel Cell Suitable For A Car Exist?
Intelligent Energy is a British company based in Loughborough.
This is their mission statement on their web site.
Focused on the development of lightweight, high efficiency, hydrogen fuel cell systems.
They also have this product page for a 110 KW fuel cell tailored for automotive use, that weighs 240 Kg.
I suspect if Ford asked for a fuel cell for a hydrogen Fiesta, that Intelligent Energy could provide one.
And I suspect other fuel cell companies could!
How Much Is The Kinetic Energy Of A Car Like This At 100 mph?
Using Omni’s Kinetic Energy Calculator, I get a figure of 422 Wh.
This figure means a battery of perhaps 2 KWh would handle regenerative braking and provide stationary power to get the car started.
Conclusion
From what I have written here, I believe that a hydrogen-powered small car is possible.
