Abstract
An electrolyte has a core and at least one projection extending from the core. The core is supported on a substrate, and the at least one projection is separated from the substrate.
Claims18
A method for making at least one freestanding electrolyte for use with a thin film fuel cell comprising the steps of:
- forming a first structure on a substrate;
- forming at least one chamber in said first structure, said at least one chamber defining a core and at least one projection extending from said core;
- filling said at least one chamber with electrolyte material;
- and
- removing said first structure to expose a freestanding electrolyte having a core and at least one projection extending therefrom, said at least one projection separated from said substrate.
