Hybrid polymer composite bipolar plates for PEM fuel cells
Анотація
Hydrogen is widely recognised as a key energy carrier for achieving EU climate neutrality by 2050, positioning hydrogen-powered PEM fuel cells as an important clean-energy technology due to their fast start-up, high efficiency, and zero emissions [1]. Within PEMFCs, bipolar plates (BPs) are essential components; nevertheless, they are also the main contributors to weight, size, and cost [2]. Polymer–carbon composites have emerged as a promising alternative to the traditional materials, carbon and metal, because they offer tunable properties and easier manufacturing [3]. However, single-filler graphite composites often fail to meet DOE targets for electrical conductivity (> 100 S cm-1) and flexural strength (> 40 MPa) simultaneously [4,5].
