Abstract
Methods, systems, and articles relating to enhanced bonding of layers in a planar fuel cell. A planar fuel cell having a composite layer is bonded to an outer layer (e.g., a fuel or fluid manifold) using intrusions that extend through an electrolyte layer and into an underlying layer (e.g., a substrate component or a current-collector component).
Claims18
A planar fuel cell assembly comprising:
- a composite layer that includes a plurality of interconnect components and a plurality of ion-conducting components;
- a plurality of electrode components disposed on a first side and a second side of the composite layer, the electrode components including a plurality of anode components and a plurality of cathode components, wherein the first side is opposite the second side;
- at least one intrusion formed in the first side of the composite layer, the at least one intrusion extending completely through a first electrode component and partly through the interconnect component underlying the first electrode component;
- a first bonding component disposed in the at least one intrusion and contacting the first electrode component and the interconnect component underlying the first electrode component;
- and
- a fluid manifold disposed over the at least one intrusion and bonded to the composite layer by the first bonding component.
