Apple Hydrogen Fuel Cell Battery Plans Revealed

51. Could use a Metal Hydride for the hydrogen fuel storage.

This is a material which can in simple terms soak up hydrogen like a sponge soaks up water.

Slight heating is required to release the hydrogen for use by the fuel cell stack to make electricity from the hydrogen and oxygen.

They could recharge these fuel storage devices in an external electrolysis unit much like plugging a battery pack into a recharger now, except the hydrogen recharger would break up water into hydrogen and oxygen, and store the hydrogen in the metal hydride tank.

There are also fuel cell designs which can be powered directly from Alcohol. There were prototypes where you put an eyedropper of Vodka and water into your storage tank and your laptop or phone would be powered for hours.

There are also designs to run fuel cell stacks from Anhydrous Ammonia which is also very dense storage of hydrogen.

Toyota and Honda both have an active Fuel Cell Vehicle development program. Both have promotional videos on youtube that have been released in the last few months.

My guess in that they are going for a Metal Hydride storage system, as otherwise it would take a very high (thousands of psi) to store enough hydrogen to be practical.
