SiGNa Chemistry sodium silicide might power your next fuel cell


We’ve been promised portable fuel cells for years, but tech from SiGNa Chemistry might have a real shot at taking the concept mainstream. Instead of the more commonly used methanol, the outfit serves up a sodium silicide mix which it’s begun licensing to companies bearing the “SiGNa fueled” logo. One example is PowerTrekk that first went on sale in Europe last December and is now making its way to the US this spring.
