Fuel cells and related assemblies involving directionally independent channels are provided. In this regard, a representative fuel cell stack () includes: a first fuel cell () having channels () associated with an anode; and a second fuel cell (), located adjacent the first fuel cell, having channels () associated with a cathode, the channels associated with the cathode exhibiting directional independence () with respect to the channels associated with the anode. A ribbed, three plate (), assembly () may provide fuel reactant and anode coolant flow channels having a first parallel orientation () and oxidant reactant and cathode coolant flow channels having a second parallel orientation independent of and different () than the first orientation. 1100. A fuel cell stack () comprising:{'b': 102', '116', '216', '316', '156', '256', '356, 'a first fuel cell () having channels (, , ; , , ) associated with an anode; and'}{'b': 101', '128', '228', '328', '158', '258', '358', '344, 'a second fuel cell (), located adjacent the first fuel cell, having channels (, , ; , , ) associated with a cathode, the channels associated with the cathode exhibiting () directional independence with respect to the channels associated with the anode.'}2100. The fuel cell stack () of claim 1 , wherein:{'b': 116', '216', '316, 'at least some the channels (, , ) associated with the anode are fuel channels operative to route fuel;'}{'b': 128', '228', '328, 'at least some of the channels (, , ) associated with the cathode are oxidant channels operative to route oxidant; and'}{'b': '344', 'at least some of the oxidant channels exhibit directional independence () with respect to the fuel channels.'}3100. The fuel cell stack () of claim 1 , wherein:{'b': 156', '256', '356', '158', '258', '358, 'at least some of the channels associated with both the anode and the cathode are coolant channels (, , ; , , ) operative to route coolant; and'}{'b': 158', '258', '358', '156', '256', '356, 'at least some of the ...
