Fuel cell power generation system and method for powering an electric vehicle

摘要

A fuel cell power generation system for powering an electric vehicle. The system comprises a low temperature fuel cell, a reactor comprising a reformer for converting hydrogen-containing fuel into a reformate gas comprising a hydrogen gas stream and a by-product gas stream. The reactor further comprises and a metal membrane separator for separating the hydrogen gas stream from the by-product gas stream. A metal hydride buffer is provided in line between the fuel cell and the membrane separator. The metal hydride buffer is capable of selectively storing hydrogen from the hydrogen gas stream and releasing the hydrogen.
