fuel cells

Fuel cells are devices that produce energy through a chemical reaction between a fuel, usually hydrogen, and an oxidizing agent. They are different from batteries in that they require a constant source of fuel, and will never stop producing electricity as long as the supply continues. Fuel cells are commonly stacked on top of each other to increase overall energy production. One advantage of fuel cells is that their byproducts don’t produce much pollution.


CER studies a type of fuel cell called a solid oxide fuel cell (SOFC), and focuses on three areas:

  1. Fundamental research on cell components and cell-stacks
  2. Experimental and theoretical studies to solve key performance and stability issues
  3. Development of innovative concepts to reduce cost, improve durability, and increase SOFC system efficiency.

Our Hydrogen Powered Toy Car

Become our customer and we will send you one. Fully self-sustained, powered by the sun , runs on green Hydrogen produced from water.

Turn on your hydrocar fuel cell car and watch it go as the hydrogen and oxygen are recombined in the efficient fuel cell to produce a DC current that powers the car’s motor. This process can be repeated again and again!

The Hydrocar is designed to independently operate in circles and maneuver around obstacles. The flashing blue LED light in its cockpit indicates that the fuel cell is producing energy. Its next-generation reversible polymer electrolyte membrane (PEM) fuel cell is designed to operate with lower-pressure hydrogen, which allows for a simpler onboard refueling design. Scientists are working to apply similar technology and power sources on a larger scale with full-size cars.
