DOI: 10.1016/j.jpowsour.2016.11.079
Abstract: Abstract Operating a PEMFC with a dead-ended anode may lead to local fuel-starvation because of water and possibly nitrogen accumulation in the anode compartment. In previous works, we used a segmented linear cell with reference… read more here.

DOI: 10.1080/15435075.2020.1722133
Abstract: ABSTRACT When the proton exchange membrane fuel cell (PEMFC) works in the mode of dead-ended anode (DA), the water and the nitrogen in the cathode flow channel will diffuse, and accumulate, to the anode flow… read more here.
