Roll-To-Roll Manufacturing For Bipolar Plates Set To Unlock Potential Of PEM Fuel Cells
Bipolar plates form the backbone of proton exchange fuel cells and consequently capture a significant portion of the fuel cell stack value, with IDTechEx forecasting their market value to exceed US$2.4 bn by 2033. A major talking point for bipolar plates is the choice of material – metal or graphite – with both alternatives holding the upper hand for certain applications. However, an often-overlooked aspect of bipolar plates is the various manufacturing routes available. In this article, IDTechEx discusses some of the different options and the seemingly inevitable convergence to roll-to-roll p...
