What this contract is for

A Cleaner, Tunable Alternative for Hydrogen Fuel Cells and Water Electrolyzers Hydrogen energy systems depend on a small but critical polymer layer inside each electrode, called an ionomeric binder, that shuttles protons, manages water and lets reactant gases reach the catalyst. The industry has long relied on perfluorosulfonic acid (PFSA) materials for this role, which contain PFAS (per? and polyfluoroalkyl substances) — “forever chemicals” — now under increasing regulatory pressure. Researchers at Los Alamos National Laboratory have developed a family of highly sulfonated poly(norbornene) ionomers that are entirely PFAS-free, deliver strong proton conductivity, do not poison precious-metal catalysts the way conventional aromatic alternatives do, and can be chemically tuned to keep electrodes dry under load. Together, these qualities position the material as a drop-in path forward for high-performance proton exchange membrane (PEM) fuel cells and water electrolyzers in a tightening environmental landscape. How it Works PFAS-Free Sulfonated Poly(norbornene) Ionomeric Binders are a class of aliphatic sulfonated poly(norbornene) polymers designed specifically as electrode ionomers in proton-conducting devices. The polymer’s backbone is built from fused bicyclic norbornane units that lack the aromatic pi-electron systems found in conventional hydrocarbon ionomers. The absence of those electrons means the polymer does not strongly adsorb onto platinum catalyst surfaces, so catalytic activity is preserved. Sulfonic acid groups covalently attached onto this backbone supply the proton-conducting pathways, while the bulky bicyclic rings create extra free volume inside the polymer, allowing oxygen and hydrogen to diffuse more easily through the binder layer and reach the catalys...

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
Check the set-aside listed above and confirm your business actually qualifies for it before you spend time on a proposal. See our guide to set-asides if the category is unfamiliar.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
