Canon patents fuel cell-powered cameras

Eagle eyes on the Web have spotted a patent filed by Canon for a technology that uses fuel cell to power dSLRs instead of the conventional Lithium-ion batteries.

For those who are not too familiar with fuel cell, it is often mentioned as a greener alternative power source, with some cars already running on it. Another interesting fact about fuel cells is that unlike traditional batteries that supply a constant voltage, the current for the former will fluctuate in accordance to the device's needs.

What this means for Canon is that its cameras, if powered by fuel cells, can draw power from the source more effectively, leading to a longer-lasting battery while at the same time saving Earth.

Although the patent didn't state what the new battery or power pack may look like, people are already speculating that it could appear like the battery grips for dSLRs.
