A process for improved performance in at least one fuel cell, having a loss in power output of at least 5% of an initial power output, wherein the fuel cell comprises a cathode, an anode, an anode chamber, a cathode chamber, a fuel comprising an anolyte that flows through the cell, and a catholyte gas, wherein the fuel cell is connected to an external load, and wherein the process includes the steps of taking the load off the fuel cell; and applying an external electric field from an external power source to the fuel cell to reverse electrochemical reactions until at least 5% of the lost power output is regained. Purging the fuel cell further enhances regeneration of the cell.

Method for regeneration of performance in a fuel cell

A method for making a shaped article or a shaped article having a volume resistivity of less than 10ohm-cm with a desired combination of properties and processibility in an injection moldable composition. In particular the shaped articles formed include injection molded bipolar plates as current collectors in fuel cell applications.

Injection moldable conductive aromatic thermoplastic liquid crystalline polymeric compositions

Disclosed is a novel fluid flow field plate for use in a solid polymer electrolyte fuel cell. The flow field plate is made of a suitable electrically conducting material and comprises a substantially planar surface, a flow field formed in said substantially planar surface, said flow field comprising a plurality of staggered lands defining a network of substantially symmetric interconnected orifices and diagonal channels in the flow field and a fluid supply manifold through which fuel and an oxidant are introduced to the flow field and a fluid exhaust manifold through which reaction by-products and excess fuel and oxidant are removed from the flow field. Streams of the fuel, oxidant and reaction by-products are continually separated and diverted into separate channels, and the separated streams are then mixed with streams from adjacent channels in the orfices.
