The choice between hydrophilic and hydrophobic versions depends entirely on how you need your electrolyte and gases to move through the electrode. The primary difference is the presence of Polytetrafluoroethylene (PTFE), commonly known as Teflon.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHydrophobic Toray Paper\u003c\/strong\u003e: This is \"wet-proofed\" with PTFE (typically 5% to 30% by weight).
