Abstract
An electrochemical cell electrode is produced by applying a plurality of thin layers of a catalyst material onto a substrate, filtering and compacting the layers between additions, until a desired catalyst amount is achieved. The catalyst bearing substrate is then dried and sintered to form an electrode. Utilizing a serial application technique minimizes surface cracking while maximizing throughput by allowing automation of the electrode production process.
