An electrochemical cell for testing the electrochemical behavior of a plurality of materials comprises: a first electrode; a counter-electrode bearing an electrochromic material having a visual or measurable property which changes in a manner proportional to the total charge passed through it; and an electrolyte between and in electrical contact with the first electrode and the counter-electrode; wherein one of the first electrode and the electrolyte comprises a plurality of regions, each region comprising a sample of material to be tested, the regions being, in the case of the first electrode, electrically connected to a common terminal. Such a cell can be used for a 'combinatorial chemistry' approach to testing the properties of possible cell components.

Electrochemical cell for testing the electrocatalytic behavior of multiple materials

An electrochemical cell comprising a cathode, an anode and an electrolyte is provided, wherein: the cathode comprises mesoporous nickel having a periodic arrangement of substantially uniformly sized pores of cross-section of the order of 10to 10m; and the anode comprises a mesoporous material having a periodic arrangement of substantially uniformly sized pores of cross-section of the order of 10to 10m and selected from: carbon, cadmium, iron, a palladium/nickel alloy, an iron/titanium alloy, palladium or a mixed metal hydride.

Electrochemical cell fabricated via liquid crystal templating

A method of preparing a porous film comprises electrodepositing material from a mixture onto a substrate, the mixture comprising: (I) a source of metal, inorganic oxide, non-oxide semiconductor/conductor or organic polymer, (II) a solvent such as water; and (III) a structure-directing agent such as octaethylene glycol monododecyl ether in an amount sufficient to form an homogeneous lyotropic liquid crystalline phase in the mixture. Electrodepositing the film from a lyotropic liquid phase in this manner provides a porous film having a substantially regular structure and substantially uniform pore size. Following deposition, the porous film may be treated to remove the structure-directing agent. The porous film may optionally be subjected to further treatment such as the electrochemical or chemical insertion of ionic species, the physical absorption of organic, inorganic or organometallic species, or the electrodeposition, solution phase deposition or gas phase deposition of organic, inorganic or organometallic species.
