Gallery: Breakthrough Process Increases Efficiency in Hydrogen Fuel Cel...

 

Researchers at Purdue University have discovered a new highly efficient technique for making hydrogen fuel cells for vehicles. Dubbed hydrothermolysis, the new process uses a high hydrogen-content powdered chemical called ammonia borane and combines two hydrogen generating processes — hydrolysis and thermolysis — to achieve conditions appropriate for use in vehicles. The technology has the potential to be twice as effective as current fuel cells at around half the temperature, and instead of requiring pressures of 5,000 psi like most hydrogen fuel cells today, this process requires a measly 200 psi.

    Good to see hydrogen continuing to move forward. The electric car movement has stifled the hydrogen movement. This graphic does good job of illustrating why hydrogen is the best non fossil fuel option. Basically the best option overall.

    Your story is a bit confusing and not entirely a correct interpretation. The discovery of Purdue University is NOT a new way of producing Hydrogen Fuel Cells. What they discovered is a new method of hydrogen STORAGE in a chemical component, reducing volume and weight. Furthermore, fuel cells do not operate at 5,000 psi. The 5,000 psi is the pressure used for hydrogen storage (compressed gaseous hydrogen).
