The present invention relates to an electrochemical device. The device features an anode constructed of materials such that the device can be chemically recharged. In addition, the device is capable of switching between operating as a fuel cell or as a battery. The switch can occur without cessation of electrical output. In certain aspects of the invention, the device is capable of operating at a temperature of less than 1000&#xb0; C. Other aspects feature a liquid anode which allows higher output, dispersion of fuel and minimal stresses in an interface comprising the anode. Preferably the anode is a liquid at a temperature of less than 1000&#xb0; C. The invention also relates to methods for energy conversion in which a continual electrical output can be produced in both the presence of fuel without anode consumption or the absence of fuel.

Electrochemical device and methods for energy conversion

The present invention generally relates to electrochemical devices such as fuel cells and, in particular, to various component configurations including configurations for converting common fuels directly into electricity without additional fuel reforming or processing. Certain aspects of the invention are generally directed to configurations in which an anode of the device surrounds the electrolyte and/or the cathode of the device. In some embodiments, all single cells in a fuel cell stack share a common anode fuel chamber. The anode, in some cases, may be exposed to a fuel. In one set of embodiments, the anode of the device may be fluid during operation of the fuel cell, and in some cases, a porous container may be used to contain the anode during operation of the fuel cell. Other aspects of the invention relate to methods of making such devices, methods of promoting the making or use of such devices, and the like.
