What are the biggest problems with fuel cells as a technology?
There are definitely safety concerns with storing explosive, pressurized hydrogen. But with smart design solutions, these safety issues are manageable. Arguing against hydrogen as a fuel source is a waste of breath, because the technology is sound. We just need to figure out how to make it affordable. Manufacturers are working to reduce costs by reducing the amount of expensive precious metals in the fuel cell membrane, and economies of scale will [also] bring costs down. In terms of public perception, the range of hydrogen vehicles is a problem. At this point, fuel cells can get about 150 miles per filling. The next generation in development will get closer to 250 miles per filling, but manufacturers need to up that to 300 or 350 miles to meet consumer expectations.

A FUEL CELL DOES NOT RUN DOWN OR REQUIRE RECHARGING; IT WILL PROD
