ACAL Energy Ltd is a leading developer of PEM Fuel Cell technology, powered by the company's proprietary platinum free cathode technology (FlowCath~R). The company is developing catalyst and sub-system technology for automotive and stationary power. The basis of the technology is an aqueous solution-based redox-type cathode, with standard anode and membrane. On the cathode side, the membrane is in contact with the aqueous catholyte solution. The electrode is typically porous carbon, through which the solution passes. The solution contains a dissolved redox catalyst species, a polyoxometalate, which carries out the redox processes, being reduced at the electrode before being circulated to a regenerator where the catalyst species is reoxidized by oxygen from air.
