Air delivery is the largest parasitic power loss in typical PEM fuel cell systems. Integrated wicks for water management can help minimize this loss by enabling low stoichiometric airflow rate operation in parallel channel (low pressure drop) flow field architectures. In this work, we develop a novel water management wick design and fabrication procedure. This in-situ polymerized wick design is adaptable to existing state-of-the-art separator plates; and can be integrated into a wide variety of flow field structures (including stamped stainless steel or injection molded plates).
