Meet Our Heroes

While fictional superheroes tend to get their powers from radioactive animals or experiments gone wrong, our cars, boats, traffic sensors, and many other objects still rely on traditional battery power. German chemical engineer Manfred Stefener wants to change that. He was part of the team that invented the first fuel cell for portable use – the direct methanol fuel cell. These fuel cells deliver efficient, reliable, and clean electricity, and could render traditional battery power supplies obsolete.
