Flexible fuel cell using stiffness-controlled endplate
Abstract(#br)We investigate the use of stiffness-controlled polydimethylsiloxane (PDMS) endplates with Young's modulus of 7.50 × 10 5 Pa and 8.68 × 10 5 Pa for improving the performance of flexible fuel cells. The maximum power densities of stacks with PDMS endplates with Young's modulus of 7.50 × 10 5 Pa and 8.68 × 10 5 Pa are 82 mWcm −2 and 117 mWcm −2 , respectively. The flexible fuel cells produce a maximum absolute power of 1.053 W (i.e., the power density is 117 mWcm 2 ) under a bending radius of 15 cm.
