摘要： The present invention relates to non-stick coatings exhibiting both excellent abrasion resistance and food release, the coatings comprising a primer layer adhered to a substrate, a midcoat layer adhered to the primer layer, and a topcoat layer adhered to the midcoat layer, the primer layer containing and encapsulating large ceramic particles spaced apart from one another and extending into the midcoat layer, the midcoat layer being reinforced and being thicker than the primer layer, whereby the ceramic particles anchor the topcoat layer from being abraded away, the topcoat layer instead becoming integrated with the midcoat layer.

摘要： The present invention provides a membrane electrode assembly for an organic/air fuel cell comprising a proton exchange membrane, an anode electrode, and a cathode electrode. The proton exchange membrane is made of a highly fluorinated ion-exchange polymer, and it has opposite first and second sides. The anode electrode is comprised of an anode electrocatalyst and a highly fluorinated ion-exchange polymer binder, and the anode electrocatalyst is comprised of platinum and ruthenium supported on particulate carbon. The cathode electrode is comprised of a cathode electrocatalyst and a highly fluorinated ion-exchange polymer binder, and the cathode electrocatalyst is comprised of platinum and cobalt supported on particulate carbon. The invention is also directed to a process for operating such a membrane electrode assembly in an organic/air fuel cell.
