This 4 months feasibility project between ACAL Energy (innovative fuel cell technology) & Thomas Swan (major UK supplier of sub contract chemicals) will make an assessment of options for a feasible, economic scale up route for AE’s new catalyst system, designed to deliver the performance requirements for the automotive fuel application. It will initially make an assessment of the alternative synthesis routes, complete the pre-production process steps to the manufacturing steps and deliver a report on the scaled up cost implications of the chemistry for mass market application. If successful this project not only enables Thomas Swan to apply their chemical manufacturing capability to provide a step change in volume & cost of production routes for this new chemistry, it will also develop the UK based supply chain for what will be a critical, strategic component in this novel fuel cell technology approach.

There is provided a method of regenerating a catholyte solution in a redox fuel cell, comprising the steps of: providing a redox fuel cell comprising a catholyte solution; providing droplet formation means for catholyte solution atomisation; atomising, by way of the droplet formation means or other means, the catholyte solution, thereby generating a mist of fine droplets; feeding the mist of fine droplets into an oxidant stream; regulating the oxidant stream flow so that time of flight of the droplets is sufficient to accomplish required mass transfer; reaching sufficient time of flight; and providing separation means for separating the mist of fine droplets from the oxidant stream. A regeneration zone, a fuel cell, and use of the regeneration zone are also provided.
