发明名称 Protecting a PEM fuel cell catalyst against carbon monoxide poisoning
摘要 An anode structure comprises an array of carbon nanotubes having a diffusion side and a membrane side, and catalyst particles interspersed on inner surfaces of the membrane side of the carbon nanotubes. The carbon nanotubes have an average diameter greater than the size of the hydrogen molecule but smaller than the size of the carbon monoxide molecule. Thus, hydrogen flowing toward the catalyst particles interspersed inside the carbon nanotubes are able to go through, while the flow of trace amounts of carbon monoxide contained in the hydrogen is blocked, preventing the poisoning of the catalyst particles by the carbon monoxide. A fuel cell utilizing the anode structure and a method for manufacturing the anode structure are also disclosed.
