Unlike Pt\/C, which uses carbon as a scaffold, Platinum Black is composed of pure, finely divided metallic platinum.\u003c\/p\u003e\n\u003cp\u003eWoven carbon cloth is favored for its 3D architecture and durability. (1) \u003cstrong\u003eFlexibility\u003c\/strong\u003e: It can be bent and compressed without cracking, making it ideal for \"home-built\" cells or flexible devices. (2) \u003cstrong\u003eMass Transport\u003c\/strong\u003e: The macro-pores between the woven threads allow for excellent liquid water removal. This is critical if the electrode is used as a fuel cell cathode where water is a byproduct. (3) \u003cstrong\u003eLoading\u003c\/strong\u003e: Platinum Black can be \"slurried\" and deeply embedded into the weave, creating a very thick, high-capacity active layer.\u003c\/p\u003e\n\u003cp\u003eCarbon paper (like Toray or Sigracet) is the standard for precision and consistency. (1) \u003cstrong\u003eUniformity\u003c\/strong\u003e: It provides a perfectly flat surface, ensuring that the distance between the anode and cathode is exactly the same across the entire cell. (2) \u003cstrong\u003eOhmic Resistance\u003c\/strong\u003e: It generally has lower through-plane resistance than cloth, making it better for high-efficiency, high-current-density stacks. (3) \u003cstrong\u003eFragility\u003c\/strong\u003e: It is brittle.
