    Advantages of high purity (99% v/s 97%)

    Exhibits greater stability

    Delivers a more controllable release of hydrogen in fuel cell applications

    Hydrogen released is cleaner with fewer constituents for fouling of fuel cells

    High purity is necessary for high-value materials, coatings and composites
