A fuel cell module is provided having a fuel cell stack, a parasitic load connectable across the electrodes, and a reactant reservoir for storing an amount of a first reactant such as hydrogen. When the fuel cell module is shutdown, the stored amount of the first reactant can be drawn to react with an amount of a second reactant (e.g., oxygen in air) remaining in the stack to electrochemically consume the first and second reactants, thereby leaving a mixture that substantially comprises a non-reactive agent (e.g., nitrogen), thereby passively blanketing the electrodes. The parasitic load limits the voltage of the fuel cell stack and induces the electrochemical consumption of the first and second reactants remaining in the stack during shutdown. A pressure gradient between the electrodes and an optional check valve may allow for movement of the non-reactive agent between electrodes. A process related to said fuel cell module is also provided.
