Fuel cell: hybrid experience leading to the car of the future

Posted by: on November 14th, 2014 Comments Off

 

Thanks to its hybrid knowledge, Toyota created the first fuel cell production car. It is a vehicle driven by an electric motor powered by the electricity generated by the chemical reaction between on-board hydrogen and airborne oxygen. Compared to the Prius, the new Toyota Fuel Cell Sedan has replaced its combustion engine by a fuel cell stack and its fuel tank by a hydrogen tank. Two high-pressure tanks actually, that store the hydrogen at a pressure up to 700 bar and that can be filled up in about 3 minutes. The only emission is water.

Hydrogen + Oxygen --> Electricity + Water

 

Built on the hybrid architecture, the Toyota Fuel Cell Sedan features a battery, a boost converter, an electric motor and a power control unit for the handling of the 4 different phases of working.

At very low load driving, meaning at very low speeds or in traffic jams, it is the battery only that provides the energy to drive the car.

At low load driving, meaning at low speeds like in city centres, the fuel cell stack provides enough energy for feeding the electric motor and simultaneously charging the battery.

At high load driving, when a lot of power is required, the fuel cell stack and the battery work together in order to boost the acceleration.

And then, as for a hybrid car, energy is recovered during braking and used for recharging the battery.
The fuel cell stack is composed by hundreds of cells. In each cell it works as follows:

1. Hydrogen is supplied to the anode side.
2. Hydrogen molecules activated by the anode catalyst release electrons.
3. The electrons released from hydrogen travel from the anode to the cathode, creating an electrical current.
4. Hydrogen molecules that released electrons become hydrogen ions and move through the membrane
5. Hydrogen ions bond with oxygen and electrons on the cathode catalyst to form water.

By generating its own electricity from hydrogen, the fuel cell car can help make a future hydrogen based society a reality, and contributes to energy diversification.

New 2014 Yaris - From Europe with Love

Designed at Toyota’s European Design Centre, the new Yaris was created in France by European Engineers for European customers.

Discussing the new 2014 Yaris, Alessandro Massimino, Product Manager at Toyota Motor Europe said: “Yaris has always been a very powerful proposition from a rational perspective: great packaging, durability, cost of ownership… And we’ve had an extremely positive response to the hybrid version. So, with the new 2014 Yaris, we wanted to go one step further: to create a vehicle that would appeal not only to our customer’s brains, but also to their hearts.’

Let`s see what surprise we were looking for…
