  • Method of operating a fuel cell wherein hydrogen is generated by providing iron in situ
    Patent number: 5510201
    Abstract: An improved system for generating hydrogen fuel for use in an energy-producing device such as a fuel cell or heat engine is disclosed. The hydrogen is produced at a faster rate by reacting particles of an activated iron reactant with heated water in a fluidized bed-type reactor. The reaction results in an increased rate of hydrogen production along with spent metal oxide particles which are easily and cheaply regenerable.

  • Methods of making oxygen distribution members for fuel cells
    Patent number: 5445904
    Abstract: A water-pervious oxygen distribution member for a hydrogen fuel cell is made by a method comprising chemical surface treatment of a carbonaceous member to impart hydrophilicity while retaining mechanical strength and electrical properties. The oxygen-distribution member produced provides unobstructed passageways for oxygen to access the cathode while permitting water to egress through porosity of the member.
