Nissan develops world’s first SOFC-powered vehicle system that runs on bio-ethanol electric power

Nissan has announced that it is currently researching and developing a Solid Oxide Fuel-Cell (SOFC)-powered system that runs on bio-ethanol electric power.

 The new system — a world first for automotive use — features an e-Bio Fuel-Cell with an SOFC power generator. SOFC is a fuel cell utilising the reaction of multiple fuels, including ethanol and natural gas, with oxygen to produce electricity with high efficiency.

The e-Bio Fuel Cell generates electricity through the SOFC (power generator) using bio-ethanol stored in the vehicle. The e-Bio Fuel-Cell utilises hydrogen transformed from fuel via a reformer and atmospheric oxygen, with the subsequent electrochemical reaction producing electricity to power the vehicle.

Unlike conventional systems, e-Bio Fuel-Cell features SOFC as its power source, affording greater power efficiency to give the vehicle cruising ranges similar to gasoline-powered cars (more than 600km). In addition, the e-Bio Fuel-Cell car’s distinct electric-drive features — including silent drive, linear start-up and brisk acceleration — allow users to enjoy the joys and comfort of a pure electric vehicle (EV). 

Fuel-cell systems use chemicals that react with oxygen, generating power without release of harmful byproducts. Bio-ethanol fuels, including those sourced from sugarcane and corn, are widely available in countries in North and South America, and Asia. The e-Bio Fuel-Cell, using bio-ethanol, can offer eco-friendly transportation and create opportunities in regional energy production, while supporting existing infrastructure.

When power is generated in a fuel-cell system, CO₂ is usually emitted. With the bio-ethanol system, CO₂ emissions are neutralised from the growing process of sugarcane making up the bio-fuel, allowing it to have a ‘Carbon-Neutral Cycle’, with nearly no CO₂ increase whatsoever.

The future of e-Bio Fuel-Cell

In the future, the e-Bio Fuel-Cell will become even more user-friendly. Ethanol-blended water is easier and safer to handle than most other fuels. As this will remove limits on creating a totally new infrastructure, it has great potential for market growth.

Nissan says running costs will be remarkably low — on par with today’s EVs, ultimately benefitting the public as well as businesses, because the e-Bio Fuel-Cell is an ideal fit for wider customer needs because of the short refueling time and ample power supply that can support a range of services such as refrigerated delivery.

The e-Bio Fuel-Cell will realise the concept of ‘Nissan Intelligent Power’, promoting greater efficiency and electrification of cars, alongside battery EVs, such as the Nissan Leaf, e-NV200, and e-Power, which is equipped with an engine housing an exclusive large-capacity motor and power generator.
