Abstract Scope Magnesium borohydride, Mg(BH4)2, has potential to meet requirements for practical PEM fuel cell applications. However, due to very slow kinetics, direct hydrogenation of bulk magnesium diboride, MgB2, to Mg(BH4)2 has only been demonstrated at forcing conditions of over 900 bar and 400 oC. We have found innovative approaches to drastically lower the hydrogenation temperature and/or pressure of MgB2, through using various inorganic and/or organic additives. Our recent results demonstrate hydrogenation of the modified MgB2 to Mg(BH4)2 at temperatures and pressures as low as 250 oC and 160 bar. PEM fuel cells utilize atmospheric air as cheap oxygen source for the cathodic reaction when generating energy. However, acid gas contaminants in air (e.g H2S and SO2) can lead to severe reduction in fuel cell performance, especially in environments with elevated levels of contaminants. Herein we report our efforts to develop alternate acid gas absorbents incorporating ionic liquids and inorganic salts.
