The ordinate indicates the voltage drop on air cathode
in relative to Hg/HgO reference electrode. The lower
the voltage drops, the lower the internal resistance
of air cathode, and the lower the internal resistance
of the fuel cell. This is the reason how Powerzinc’s
zinc-air fuel cell is able to provide both high
power density and high energy density. |

and have high current density, which enable the
zinc-air fuel cell to operate in high power.
