More Durable Fuel Cells For Hydrogen Electric Car

Take a ride on the University of Delaware’s (UDFuel Cell bus, and you see that fuel cells can power vehicles in an eco-friendly way. In just the last two years, Toyota, BMW and Honda have released vehicles that run on fuel cells, and carmakers such as GM, BMW and VW are working on prototypes.  If their power sources lasted longer and cost less, fuel cell vehicles could go mainstream faster. Now, a team of engineers at UD has developed a technology that could make fuel cells cheaper and more durable.

Hydrogen-powered fuel cells are a green alternative to internal combustion engines because they produce power through electrochemical reactions, leaving no pollution behind. Materials called catalysts spur these electrochemical reactions. Platinum is the most common catalyst in the type of fuel cells used in vehicles. However, platinum is expensive — as anyone who’s shopped for jewelry knows. The metal costs around $30,000 per kilogram. Instead, the UD team made a catalyst of tungsten carbide, which goes for around $150 per kilogram. They produced tungsten carbide nanoparticles in a novel way, much smaller and more scalable than previous methods.

The material is typically made at very high temperatures, about 1,500 Celsius, and at these temperatures, it grows big and has little surface area for chemistry to take place on,” explains Vlachos, professor at the Catalysis Center for Energy Innovation (UD). “Our approach is one of the first to make nanoscale material of high surface area that can be commercially relevant for catalysis.”

The researchers made tungsten carbide nanoparticles using a series of steps including hydrothermal treatment, separation, reduction, carburization and more. The results are described in a paper published in Nature Communications.

Hello Hydrogen, Bye Bye Gasoline

Range: 300 miles (480 km)
Top speed: 100 mph (160 km/h)
Lease terms: $500/month (360 euros); $3000 down (2150 euros)
Free fuel or in other term Free “gas” up

The Hyundai Tucson Fuel Cell SUV will be the first mass-produced hydrogen car in the U.S. Next month Californians can buy it.
It shows as well that hydrogen electric car may win the competition against cars powered by electric batteries.

Because hydrogen fuel infrastructure is more or less non-existent, Hyundai’s rollout will be small. The car will be available at select dealers in Southern California, all within range of the company’s sources of hydrogen, which include a nearby waste water treatment plant. Local drivers will be able to “gasup for free at any of seven distribution stations. A fill-up takes less than 10 minutes and lasts for up to 300 miles. The company claims that the Tucson charges more quickly and has a longer range than traditional EVs. It’s also clean: The only exhaust is water vapor.
