Fuel cells are an excellent opportunity to address the challenges of the energy supply of the future. The polymer electrolyte membrane fuel cell (PEMFC) stack consists of several core components such as the bipolar plates (BPP) and membrane electrode assembly (MEA).
BPPs have an influence on stack dimensions, performance and lifetime as well as costs. The challenge is to design an optimal BPP for specific applications, considering the manufacturing effort and costs. Basically, two material concepts are currently available: polymer composite materials or metals. Compared to metallic BPPs, polymer-based BPPs show a longer service life and allow a high geometrical flexibility. Metallic BPPs possess a very thin overall thickness which makes them preferable for use in commercial automotive sector. Depending on the base material, different manufacturing processes are required. This article presents a comparison and an assessment of BPPs regarding possible manufacturing processes as well as resulting costs.
