摘要： A method of manufacturing a porous structure for a fuel cell is disclosed. The method includes providing the porous structure, and processing the porous structure to selectively produce a non-porous region on the porous structure. In one example, the non-porous region is provided at the perimeter of the porous structure, an edge of an internal manifold and/or a surface or recess that supports a seal or gasket. The non-porous region has a porosity that is less than the porosity of the porous structure. The non-porous region prevents undesired leakage of fluid from the porous structure and prevents migration of adhesive associated with the seals.

摘要： A bipolar battery stack incorporating aqueous intercalation battery (AIB) materials is described. The bipolar AIB battery stack can include anode layers made from anode intercalation materials, The disclosed bipolar AIB stack can provide low impedance, rapid manufacturing, and low materials costs. Due to the inherently safe nature of the AIB materials, the requirements for heat removal are significantly relaxed and no requirements exist for cell bypass, Accordingly, the disclosed bipolar AIB stack configuration provides a durable and cost-effective energy storage battery for many renewable applications.

摘要： A membrane electrode assembly includes a membrane, an anode catalyst layer and a cathode catalyst layer. The anode catalyst layer is on a first side of the membrane and the cathode catalyst layer is on a second side of the membrane, wherein the second side of the membrane is opposite the first side of the membrane along a first axis. The cathode catalyst layer includes agglomerates formed of a catalyst support supporting catalyst particles, an agglomerate ionomer and an inter-agglomerate ionomer. The agglomerate ionomer surrounds the agglomerates and the inter-agglomerate ionomer is in regions between the agglomerates surrounded by the agglomerate ionomer. The agglomerate ionomer is different than the inter-agglomerate. Methods to produce the catalyst layer are also provided.
