Fuel Cell Cars for Expo 2010

Expo 2010 Vehicles Equipped with Fuel Cell Humidifiers from Perma Pure

FC-Series used in 100 vehicles shuttling international visitors at World Expo

Toms River, NJ (August 24, 2010) – In keeping with Expo 2010 Shanghai China’s theme, “Better City-Better Life,” green fuel cell technology was chosen to power the visitor shuttles at this year’s world’s fair. Increased productivity, zero emissions and reduced costs are just a few of the reasons small vehicle manufacturers choose fuel cells as an alternative to industrial lead acid batteries. FC-Series humidifiers from Perma Pure provide the efficient water vapor management critical to the operation of these fuel cells.

Expo 2010 Shanghai China runs from May 1 through October 31. As the largest world’s fair site ever at over 5 square kilometers, visitor transportation was a critical issue. More than 42 million people to date have visited the site, using the 100 open-air fuel cell powered mini-buses to move between exhibit pavilions.

In fuel cells, where incoming gas must be humid, Perma Pure’s FC-Series humidifiers provide durable, self-contained humidification. The humidifiers used in the expo vehicles recover water from the fuel cell exhaust and transfer it into the incoming gases by permeation through the walls of Nafion® tubing, a proprietary technology available only from Perma Pure under license from the polymer manufacturer, DuPont.

With no moving parts, there is no parasitic power load on the stack. The humidifiers provide over 10,000 continuous hours of operation in Class 1 and Class 3 trucks. The compact, lightweight units are available in a range of sizes suitable to virtually any transportation application, from wheelchairs and motorbikes to forklifts and buses.

Perma Pure (www.permapure.com) manufactures a full line of gas conditioning products including dryers, humidifiers, filters, coalescers, specialty scrubbers and complete sampling systems for use in medical, scientific and industrial applications. The company is the sole manufacturer of Nafion tubing under license from the polymer manufacturer, DuPont. Perma Pure is based in Toms River, New Jersey, with representatives and distributors around the world.
