Claim Text:
1. A fuel cell system comprising: a fuel cell; a fuel supply to supply a liquid fuel to the fuel cell; an accelerometer, wherein output from the accelerometer controls an element of the fuel supply or the fuel cell configured to stop a flow of the liquid fuel; a fuel supply connector configured to attach the fuel supply to the fuel cell; a fuel-absorbing element configured to reduce a leakage of the liquid fuel in response to a separation between the fuel cell and the fuel supply; and a retainer made from an electroactive polymer, wherein said retainer is configured to retain the fuel supply to the fuel cell system and actuatable by the output from the accelerometer; wherein the output from the accelerometer ejects the fuel supply from the fuel cell system by actuating the retainer.
