An ink for forming nanofiber fuel cell electrodes, and methods of ink formulations, and membrane-electrode-assemblies for electrochemical devices. The ink includes a first amount of a catalyst, a second amount of an ionomer in a salt form, and a third amount of a carrier polymer dispersed in one or more solvents, where a weight ratio of the first amount to the second and third amounts is in a range of about 1-1.5, and a weight ratio of the second amount to the third amount is in a range of about 1-3. The ink has a solids concentration in a range of about 1-30 wt %. Preferably, the solids concentration is in a range of about 10-15%.
