Abstract
According to the present invention there is provided a method of producing a catalyst-containing layer for a fuel cell or electrolyser. The method comprising the steps of: providing a flow of ink, the ink comprising catalyst particles, an ion-conducting polymer and a liquid medium; conveying the flow of the ink through a density separator configured to separate contaminant particles from the flow of ink, wherein the contaminant particles are more dense than the catalyst particles; and then coating the ink onto a substrate.
