Anode chambers with variable volumes

Abstract

Described herein are articles, systems, and methods relating to fuel cell systems that include anode chambers with variable volumes. The volume of the anode chamber may be relatively small or essentially zero upon start up to prevent influx of contaminants that would have to be purged from the system. As fuel is directed into the anode chamber, the chamber volume increases to accommodate the flow of fuel.

Description

technical field [0001] The subject of the invention relates to a fuel cell comprising an anode chamber with a variable volume. Background technique [0002] Generations of portable electronic devices tend to be smaller in size while providing increased performance. As electronic components are designed to be smaller in size and incorporate sophisticated and complex technologies, the requirements for the associated power supplies generally increase. For example, the power supply may need to be smaller or have a smaller footprint so that the entire device can be accommodated in additional processes or reduced in overall size. Additionally, additional processing may require the power supply to be on for extended periods of time or to deliver power at a uniform rate in order to stabilize electronic component performance. [0003] To generate electricity, fuel cell systems are typically supplied with fuel, which is consumed in fuel cell reactions to generate electricity. In so...
