Abstract

A fuel cell system (10) with a toggle switch (32) between an ON or OFF position is provided. In the OFF position, gas is purged from the fuel cell. The fuel cell (12) may surround the fuel source (14) with the cathode side of the fuel cell facing the fuel source. Additionally, both the fuel cell (12) and the fuel source (14) may have similar form factor to maximize the available space. Preferably the form factor is substantially an oval shape. The fuel cell system may also have a pressure regulator (26).
