An anonymous reader notes a development from the world of photography that could spread to notebooks and cell phones. Canon has filed for a patent on a fuel cell-powered DSLR. The fuel cell would power not only the camera body but also all accessories attached to it, doing away with the need to power flashes (for example) with AA or other batteries. The patent covers other electronic devices generally, but is clearly directed toward DSLR cameras, given the diagrams and examples used. "Canon continues to push its fuel cell development by devising a method for powering not only the internal DSLR body electronics, but also external components such as lenses and hotshoe flashes."

Water and air management[8] (in PEMFCs). In this type of fuel cell, the membrane must be hydrated, requiring water to be evaporated at precisely the same rate that it is produced. If water is evaporated too quickly, the membrane dries, resistance across it increases, and eventually it will crack, creating a gas "short circuit" where hydrogen and oxygen combine directly, generating heat that will damage the fuel cell. If the water is evaporated too slowly, the electrodes will flood, preventing the reactants from reaching the catalyst and stopping the reaction. Methods to manage water in cells are being developed like electroosmotic pumps focusing on flow control. Just as in a combustion engine, a steady ratio between the reactant and oxygen is necessary to keep the fuel cell operating efficiently.

But it seems to me from a quick read of the patent that this is exactly what this is.
It is more than an assertion that "although fuel cells can be used to power things, a camera is not a thing, hence this crap is patentable !"
It seems that some other manufacturer saw that a camera might supply power to or control and monitor the power within various strap-ons, like flash, power drive.
Canon seems to have added the idea that the camera body might also supply the fuel and monitor fuel cells within these strap-ons.

Re:A patent for what? (Score:5, Informative)
That's what I thought too, until I looked at the diagram in the article. Instead of generating all the power in the camera and sending electricity to the attached devices, they are pumping fuel from the tank in the camera to individual fuel cells in each device. That's what the patent covers, not just "insert powerplant x into device y, patent, license, profit".
Seems kinda loony and ass-backwards, but it's definitely a unique idea I suppose. I still don't know if it satisfies my definition of non-obvious. One assumes an engineer came up with this when faced with the problem about how to provide enough power for arbitrary configurations without wasting fuel generating power that doesn't get used.

what gives them the ability to patent "using a fuel cell in a camera"
The exciting thing about these new fuel cells is the form factor- they are proposing fuel cells in the shape of a small cylinder, about 50 mm long by 14 mm diameter, with the positive and negative terminals on opposing ends. You can even use more than one in a device, by connecting them in series or parallel. Have no doubt that this innovative idea is worthy of a patent (at least from the current patent office).

I am a fuel-cell researcher and when I RTFA'd I gasped—it seems they want to run this on hydrogen. They must be kidding. Normal H2 fuel cells run at about 80 C and require a hell of good cooling. Portable electronics is the domain of passive direct-methanol FCs.
Good luck selling people a can of explosive pressurised gas they have to hold close to their body, and a machine that has to heat up to 80 Celsius before it starts delivering power.
Anyway, I fail to see the inventive step in the camera. Fuel cells are not new. This type in particular does not seem new. The only new thing is that they stuffed it into a camera. Doesn't that qualify for trivial? Or can I file a patent for FC-powered drills and mixers?

Pretty gushy article: "Essentially, Canon wants its fuel cell to power everything you attach to your camera. Thatâ(TM)s right. No more AA batteries to stuff into your camera bag."
Yep, no more AA batteries, you'll just need to stuff little bottles of something like lighter fluid or butane or alcohol into your camera bag. And in order for those little bottles to be safe and not freak out TSA, they'll have to be fairly well-designed little gadgets.
And they'll need to clip neatly and securely into the camera. I betcha Canon and Nikon and Olympus will all have different and incompatible fuel canisters... and probably Canon will have different fuel canisters for different camera models. And if you don't buy a bunch and you do run out, the local camera store in the strange city will stock the fuel canisters for current models but not for your three-year-old model... and you'll need to shell out $129.95 for the adapter kit that lets you refill them from a propane cylinder, which, of course, you'll have to stuff into your gadget bag, too.

No.
"Fuel cell" refers to the module in which a membrane allows the following reaction to occur:
2H2 + 02 = 2H20
Or some variant if the reagent H2 source is a hydrocarbon.
A fuel cell will always have a reservoir of fuel, as will any engine or energy output mechanism. Thus a fuel cell can have a refillable "fuel tank" in which the user just ads the H2 source fuel, be it alcohol or some other liquid hydrocarbon.

That's just wrong, sorry. The whole idea behind a fuel cell is that it's like a battery only you fill it with fuel instead of recharging it, and they last much longer in between fillings than a a battery does between charges. Fuel cells are generally intended to be quickly refilled by the user. There are variations on the concept but that's the most common scenario. Quick refilling is one of the two main advantages of fuel cells, yet you seem to have missed that...
