Gencell Ltd
A maker of fuel-cell power systems, GenCell turns hydrogen and ammonia into clean electricity that keeps telecom towers, hospitals, and remote sites running — a quiet alternative to diesel generators. Founded in Israel in 2011, the company builds on alkaline fuel-cell technology that once powered NASA's Apollo space missions. Its name is a play on "generator" and "cell," and its systems can extract hydrogen on demand from ordinary ammonia, letting sites go off-grid without hauling fuel.
