The invention provides an electrode comprising an electrically conductive
material having a surface capable of producing surface enhanced Raman
scattering of incident light from a complex adsorbed at the surface of
the electrode, the complex including the electrically conductive material
combined with a second material that is substantially reducible and not
substantially oxidizable. The surface of the electrode can be
microroughened. The invention also includes a method for making various
embodiments of the electrode, and a method of generating electricity
using the electrode. In accordance with a further aspect of the
invention, a fuel cell is provided including the electrode of the
invention.
