Abstract: A framework for facilitating communication between a multi-cluster management (MCM) system and the clusters managed by the system is provided. According to one set of embodiments, the framework comprises two independent, unidirectional communications channels: a first channel (i.e., “intent channel”) that flows from the MCM system to each cluster, and a second channel (i.e., “data sync channel”) that flows from each cluster to the MCM system. Through the intent channel, the MCM system can deliver control information to each cluster for actuating management changes/operations therein in a manner that is robust against network dropouts and packet loss. Through the data sync channel, the MCM system can collect and process status information from each cluster (such as, e.g., object state transitions triggered by the control information sent via the intent channel) in a manner that can efficiently scale to support large numbers of clusters.

Abstract: The present invention introduces ionic polymers featuring with a spiro structure, which enhances the solubility and gas permeability of the ionic polymer while maintaining excellent conductivity, mechanical properties, and dimensional stability. This is achieved by incorporating a spiro fragment with a large free volume into the polymer backbone. As a result, the gas permeability of the catalyst layer prepared from this ionic polymer is improved, making it suitable as a catalyst binder for proton exchange membrane fuel cells (PEMFCs) or anion exchange membrane fuel cells (AEMFCs). Furthermore, the electrochemical performance of the fuel cell is enhanced. Additionally, the proton exchange membrane and anion exchange membrane derived from this ionic polymer containing a spiro structure effectively improve the conductivity of both types of membranes by increasing the space volume due to the presence of the large free volume spiro fragment.
