HIGH ENERGY DENSITY FUEL CELL APPARATUS AND SYSTEM WITH A HYDRIDE-BASED HYDROGEN GENERATOR AS A SCALABLE POWER SOLUTION CONCEPT

The application provides a high energy density fuel cell apparatus and system with at least one hydride-based hydrogen generator. The system includes an array of fuel cells that are arranged either in parallel or series. The system also includes a water storage vessel, which has a single stage hydrolysis reaction zone for hydrolyzing magnesium hydride. The hydrolysis reaction mechanism is based on the exothermic MgH2 hydrolysis reaction pathway. The system further includes a reactor vessel, a water pump disposed between the water storage vessel and the reactor vessel, and a check valve disposed in a discharge line connecting the water pump to the reactor vessel. The hydride-based hydrogen generators (single or multiples) are arranged either in parallel or series. The fuel cells, the water storage vessel and the reactor vessel are in fluid communication. Furthermore, the discharge line comprises a tubing with a predetermined rupture pressure range.
