About Superprotonic
Superprotonic was founded in 2003 based on its founders’ work at the California Institute of Technology (Caltech). Superprotonic is pioneering the use of solid acids as fuel cell electrolytes. Solid acids are solid-state materials exhibiting liquid level conductivities at intermediate temperatures (150 degrees C to 300 degrees C). Solid Acid Fuel Cells (SAFC) constitute a fundamental and radically different solution that overcomes the barriers to mass adoption of fuel cells.
