1. An ink usable for forming a fiber electrode for an electrochemical device, comprising:
a catalyst, an ionomer in a salt form, and a carrier polymer dispersed in one or more solvents, wherein the salt form of the ionomer has some or all of ion-exchange sites in a form SO3X, wherein X is a monovalent metal cation, a quaternary ammonium cation, or a multivalent cation, wherein the monovalent metal cation comprises Na+, Li+ or Cs+, the quaternary ammonium cation comprises N(CH3)4+ or N(CH2CH3)4+ and the multivalent cation comprises Ni2+ or Co2+,
wherein the catalyst comprises Pt/C;
wherein the ionomer comprises a perfluorosulfonic acid (PFSA) polymer including Nafion®,
wherein the carrier polymer comprises polyethylene oxide (PEO), and wherein PEO is about 1 wt % of a total weight of the ink; and
wherein a weight ratio of Pt/C:salt-form Nafion®:PEO is 52:37:11.
