摘要： The present invention is directed to a device, and method of operation, for a fuel cell which uses bubble-based pumping to self-pump the fuel to the anode, and a single, common channel separating the anode from the cathode through which a mixed fuel and electrolyte flow. The fuel cell includes a single channel having two of its sides formed by the anode and the cathode, each having a suitable catalyst. A bubble generating region is formed in the anode and cathode reaction area of the channel. A one-way valve is located upstream of the bubble generating region. A vent for venting bubbles is disposed over a portion of the channel downstream of the bubble generating region. The fuel cell may be advantageously used to build miniature fuel cells for miniature electronic devices, or scaled to build larger fuel cells for larger electronic devices.
