Abstract
The invention is directed to external defibrillators that are powered by fuel cells. A fuel cell provides a voltage to power components of a defibrillator, such as a processor and a user interface, and to charge an energy storage circuit, e.g., a capacitor, that stores energy for delivery to a patient as a defibrillation shock. A user may use an activator to activate the fuel cell. In some embodiments, the activator includes a button that a user actuates to cause delivery of fuel to the fuel cell.
