Summary on Grant Application Form |

A previous EPSRC Programme has resulted in the production of novel candidate copolymers by two entirely different synthesis routes; (i) Bulk Polymerisation. In this process the polymer is produced from a mixture of monomers whereby the molar ratios of each component can be varied independently to allow the properties of the final polymer to be controlled; hence separately defining the hydraulic and electrical properties of the resulting polymer. Crosslinked materials so formed are defined by the shape of the process container. They are ideally adapted to the production of Composite MEAs where the membrane polymer is required to conform to and interpenetrate the structure of the adjacent electrode, making intimate contact without additional process stages. (ii) Graft Copolymerisation. Here a pre-existing polymer is used as the structural basis of the system and suitable ionic sites (sulphonic or carboxylic) are grafted to the polymer. This process has been successfully applied to the production of thin uniform membranes and has produced cell-compatible materials of high performance. This technology can be extended to produce precursor powder of slurry copolymers able to provide intimate contact with the electrodes. It is precursor powder or slurry copolymers able to provide intimate contact with the electrodes. It is therefore proposed to develop processes (i) and (ii) to enable Composite MEAs to be fabricated.
