Abstract
A method for providing hydrogen to a hydrogen-powered device comprises providing a buffer connected to supply hydrogen to the device. The buffer is filled with hydrogen by coupling the buffer to a cartridge containing a predetermined quantity of hydrogen. The hydrogen in the cartridge may be stored in a form having a higher energy density than the hydrogen in the buffer. Systems comprising hydrogen-powered devices that include such buffers are also described.
