The good news - depending how you look at it: international regulatory agencies are going to let you carry fuel cells and certain fuels in airline passenger cabins starting in January.

The other news: The U.S. Fuel Cell Council (USFCC), apparently acting of its own accord to make lives easier for governments across the globe, wants fuel cell makers to tell them about products that fliers are likely to carry. They want to document them to make life easier for screeners and security personnel worldwide.

“If your company plans to market a fuel cell, a fuel cell powered product or a fuel cartridge in 2007 that could be transported in an airline passenger cabin, please send a photo, date of availability and product details to the USFCC for inclusion in its Air Guidance Document,” requests Robert Wichert, Technical Director of the USFCC.

Fuel cell makers: warm up your digital cameras.
