A system is disclosed to generate electric power from a chemical hydride.
A fuel cartridge produces hydrogen by reacting a liquid with a chemical
hydride. A fuel cell stack generates electric power using an oxygen
source and the produced hydrogen. An electric power storage device is
coupled with the fuel cell stack. The electric power storage device
stores and supplies electric power. One or more liquid sources inject the
liquid into the fuel cartridge at a variable rate. A controller
calculates a liquid injection rate for the one or more liquid sources
based on power demands of an electric load.
