An Assessment of Novel Graphene Foam and Graphene-Based Microporous Layers for Polymer Electrolyte Fuel Cells: Fabrication and Characterisation

摘要

Polymer Electrolyte Fuel Cells (PEFC) are electro-chemical energy conversion devices capable of providing sustainable transport, stationary and portable solutions, owing to their high-power density and fast start-up time. However, water management remains one of the largest barriers limiting fuel cell efficiency and the wide scale deployment of PEFC. The microporous layer (MPL) of PEFC is widely acknowledged as a crucial, performance enhancing component; increasing cell efficiency and durability, largely by the improved management of liquid water and two-phase flow.
