1. A method of forming a fuel cell system component, comprising:
dispensing an ink onto a substrate to form an ink layer, the ink comprising, based on the total weight of each ink:
from about 50 wt % to about 90 wt % of a fuel cell system component powder;
from about 5 wt % to about 20 wt % of propylene carbonate (PC) solvent; and
from about 0.25 wt % to about 10 wt % of polypropylene carbonate (PPC) binder; and
solidifying the ink layer to form the fuel cell system component.
