Abstract: Simple membrane electrode and frame assemblies for a solid polymer electrolyte fuel cell stack and improved methods for making them are disclosed which involve the use of a single adhesive layer. Using an appropriate design, the single adhesive layer can provide multiple bonds, including a bond between one of the gas diffusion layers and a catalyst coated membrane assembly, between the catalyst coated portion of the catalyst coated membrane assembly and the frame, and between either the other of the gas diffusion layers and the frame, or between an uncoated portion of the catalyst coated membrane assembly and the frame.

Abstract: Techniques described herein may be implemented in the context of a computing resource service provider. A machine learning (ML) service provides an interface to clients which can be used to create, read, update, and delete ML pipelines. ML pipelines can be converted to a human-readable format, which a server persists. Clients of a machine learning service can start, stop, and resume executions a ML pipeline based on the human-readable format of the ML pipeline.
