fuel-cell catalyst

fuel-cell catalyst

[′fyül ‚sel ′kad·ə‚list]
(chemistry)
A substance, such as platinum, silver, or nickel, from which the electrodes of a fuel cell are made, and which speeds the reaction of the cell; it is especially important in a fuel cell which does not operate at high temperatures.

This material shows really promising activity as a fuel-cell catalyst. While we found that the gelatin makes nanoparticles, we wanted to understand the process better in the hope that we could control the reaction and make those nanoparticles even smaller, therefore creating a more efficient catalyst.
The fund's first five investments are into blade compressor company Lontra; fuel-cell catalyst developer Amalyst; sensor company Oxsensis; fusion engineering company Tokamak Energy; and space technology business Oxford Space Systems.

For fuel cells to be used more widely, their cost has to come down, and here Ilika thinks it can play a role in developing cheaper alternatives to platinum fuel-cell catalysts, based on palladium alloys.
