Durability of Polymer Electrolyte Membrane Fuel Cell (PEMFC) Directly Hybridized with Supercapacitor Storage Devices Public

Polymer Electrolyte Membrane Fuel cells (PEMFC), modular energy conversion devices, convert the chemical energy of hydrogen directly to electrical energy efficiently and with zero emissions. We investigated the behavior of PEMFCs in cyclic operation, simulating use in transportation applications, and an accelerated aging process. This was done by requesting a range of current loads from the cell; representing typical automotive conditions. This study aimed to compare non-hybridized (without supercapacitor (SC)) FC degradation and durability with previously studied hybridized configurations. From the results, it was found direct hybridization with SC significantly increased the durability and lifetime of the FC.
