and an electrocatalyst. (Vanderborgh, Abstract).
30) Vanderborgh teaches that its electrodes can be used in fuel cells or other
devices that require electrochemical generation of electrical power from reacting
gases. Specifically, Vanderborgh states:
Throughout the description, the composite electrode of the present invention
has been characterized as suitable for assembly in a fuel cell, such as a
hydrogen/oxygen fuel cell. As will be evident to those skilled in the art, the
composite electrode of the present invention can be utilized in
electrochemical devices which produce electrical power or chemical
compounds. For example, the present invention is applicable to systems
wherein water in liquid or vapor state is electrolyzed to generate hydrogen
and oxygen, to the synthesis of chlorine which is driven by electrical energy,
or to the synthesis of other materials of commercial interest, such as the
production of organic acids from alkanes. In general, the present invention
can be utilized to fabricate electrodes useful for the electrochemical
generation of electrical power from the consumption of reacting gases or
liquids or the electrochemical generation of chemical compounds from the
consumption of electrical power.

31) Vanderborgh states that a goal of its invention is to provide a composite
electrode that uses the electrocatalyst more efficiently. (Id. at col. 3, ll. 51-55).
32) Vanderborgh teaches that it was known in the art to use composite electrodes
of ion exchange polymers, metals or carbon compounds and electrolytical
