Electrochemical mass fluxes

An electrochemical mass flux is calculated for each specie taking part in the reaction, in accordance with Faraday’s law, and taking into account whether the specie is consumed or produced:

$${{\dot{m}}^{''}}=~\pm \frac{Mi}{\nu F}$$
where M is molar mass, i is current density, ν is valence, and F is Faraday’s constant. Air species are treated separately from fuel species, and separate sums of air and fuel fluxes are accumulated for later use. The plus sign is used for products and the negative sign for reactants. On the air side, the above calculations are coded at lines 164 to 177 of solveElectrochemistry.H.
