    Enhancing the Energy Efficiency of a Proton Exchange Membrane Fuel Cell with a Dead-Ended Anode Using a Buffer Tank

    Enhancing the Energy Efficiency of a Proton Exchange Membrane Fuel Cell with a Dead-Ended Anode Using a Buffer Tank by Trung-Huong Tran, Karthik Kannan, Amornchai Arpornwichanop, Yong-Song Chen

    Published 2025-06-01

    Enhancing energy efficiency is essential for proton exchange membrane fuel cells (PEMFCs) operating in a dead-ended anode (DEA) mode. This study proposes the integration of a buffer tank, positioned between the mass flow meter and the fuel cell, to reduce hydrogen loss during purge events. The buffe...
