Publication number: 20140004436Abstract: Methods, articles, and systems for controlling the internal operating temperature of fuel cell systems, such as planar fuel cell arrays. The heat management system conducts heat away from the fuel cell without disturbing the flow of gases around the fuel cell layer and without the need for the equipment to disturb the flow of gases around the fuel cell layer. The present invention also provides a heat transfer system that has a low thermal mass relative to the fuel cell layer or is thermally isolated from the fuel cell layer such that the heat transfer system will not remove substantial amounts of heat from a fuel cell layer during star-up and can be activated to dissipate heat from the fuel cell only as needed.Type: ApplicationFiled: June 28, 2012Publication date: January 2, 2014Applicant: Societe BICInventors: Jeremy Schrooten, Jean-Louis Iaconis, Paul Sobejko, Benjamin Tam, Gerard F.

Publication number: 20130043125Abstract: A hydrogen generation system comprising a solid fuel that reacts with an aqueous liquid to generate hydrogen is disclosed. The solid fuel comprises first metallic particles coated by smaller second metallic particles, such that multiple galvanic cells are formed on a surface of the first metallic particles between the metals in the first metallic particles and the second metallic particles. The first metallic particles can be further covered by smaller third particles. An example of the solid fuel is hybrid particles formed by larger magnesium particles coated by smaller iron and silicon particles. The solid fuel may also include salt such as sodium chloride and/or a fire retardant such as potassium chloride. The salt may be added to the aqueous liquid instead. The solid fuel can be formed into fuel pellets, or can be suspended in a suspension agent to form slurries or gels.Type: ApplicationFiled: February 10, 2012Publication date: February 21, 2013Applicant: Societe BICInventors: Laura Gill, Jeremy Schrooten, Mikhail Gurin, Sally Seaman, Joerg Zimmermann, Tao Wang, Will Skrivan
