摘要: Ink dispersions for use in fuel cells, comprising a mixture of: (1) carbon-containing material, such as carbon black; and (2) base or acid operable to adjust the pH of ink dispersion, wherein has zeta potential close lying outside +/−30 mV range point zero charge. The mixtures can also include fluoropolymer, at least one alcohol, water. be used conjunction with gas diffusion media components cell, including proton exchange membrane cells. are very stable high current density applications.
