The AIP fuel cell options are classified by their electrolyte. The options researched were Molten Carbonate<br />
(MCFC), Phosphoric Acid (PAFC), Polymer Electrolyte Membrane (PEM), Solid Oxide, Direct Methanol, Alkaline,<br />
and Regenerative (Reversible). The best alternative for <strong>SSG</strong>(X) was found to be the PEM cell, providing reduced<br />
signatures and safe and proven technology. Reformers were also researched, but not considered due to their<br />
immature development.<br />
PEM fuel cells have multiple advantages. They offer a quiet low temperature operating condition, thereby<br />
reducing the thermal signature. The only byproduct is clean pure water. The technology is proven and safe;<br />
therefore, PEM fuel cells are a low risk option. PEM cells are stackable, providing a range of space options. Their<br />
disadvantage is that pure Hydrogen and Oxygen reactants must be carried. Cell impurities also reduce efficiency<br />
and output. Figure 6 displays how a PEM fuel cell operates.
