Table 2. Values of Performance Variables for the No (M1), Simplistic (M2), and Full (M3) Channel Model, with a Variable Current Density i_tot = [50–250 mA cm^–2]^a.

Model	V_cell [V]	FE_C₂H₄ [-]	χ_het [-]	χ_hom [-]
M1	3.69	0.70²⁸	0.50⁶	0.00⁶
M2	f(i_tot)	f(···)	f(···)	0.13^b
M3	f(i_tot)	f(···)	f(···)	f(···)

Performance variables which are dependent on more than one other variable are denoted as f(···).

With a fixed additional current density (i_hom = 50 mA cm^–2) and a single channel gas flow rate of 10 sccm, for more details see section S1.
