Program Pumps Up Fuel Research

As more countries on curbing carbon emissions, cars powered by hydrogen are an increasingly attractive choice. But the of the fuel cells used to hydrogen to electrical energy is far ideal. Now, a new mathematical developed by scientists at Case Reserve University and Toyota RD Laboratories in Nagakute, Japan, a tool for probing the chemical that occur inside cells. The discovery may bring cars a step closer to

Chemistry Alfred B. Anderson, at Case Reserve, has long been quantum mechanics theory—a to explain how molecules behave at the level—to understand chemical But until recently the computational available were not Sufficiently to study those reactions occur on the surface of electrodes, as in fuel cells.

In these devices, hydrogen are split into two protons and two at a negative electrode. The electrons through a wire and end up at a positively electrode, where they oxygen molecules in half. oxygens then pair up protons to create water Electrical energy is produced in the

Platinum particles on the electrodes are used to speed up, or catalyze, sluggish reactions. But because is expensive and corrodes, researchers been searching for other that can take its place.

Before they can do that, they need better for understanding the exact steps in the hydrogen and oxygen-splitting reactions and for how changing various parameters affect them. Ryosuke a scientist from Toyota RD Laboratories, joined Anderson’s lab to such tools.

Anderson had met Yu a group leader at Toyota and a Case Western Reserve student, at a meeting in 2004. “asked whether he could one of his young scientists to work in my lab for two Anderson recalls. Jinnouchi Anderson’s lab in the spring of 2006 and set to work to develop a software called Interface 1.0, combines several different for explaining and predicting chemical

With Interface 1.0, Anderson makes available to at no charge, researchers can now start to apart the reaction steps at cells’ electrodes. This can be used to make reactions efficient and find catalysts are cheaper, more active and stable than platinum. new theory has great potential for and for guiding experiments,” says
