Abstract

The present invention discloses a method of making a fuel cell component, the method comprising:

(i) providing a substrate;(ii) providing a coating composition;(iii) providing apparatus comprising a slot die configured for intermittent delivery of the coating composition to the substrate for forming an electrode on the substrate,(iv) wherein the forming includes intermittently depositing the coating composition on the substrate; and(iv) wherein the slot die is moveable between a non-coating position in which the slot die is in a first pre-determined distance relative to the substrate; and a coating position in which the slot die is in a second pre-determined distance relative to the substrate; and wherein the forming step further comprises(v) configuring the slot die for predetermined intermittent delivery of coating composition to produce an electrode on the substrate when the slot die is in the coating position.
