It is shown that each flame cell represents a separate "chemical reactor", and in the cell, the process of complete chemical transformation occurs. A cellular combustion regime of 40% H2-air mixture in the presence of Pt wire within the interval 270-350 C was observed for the first time. It is shown that the regime is caused by the catalytic action of Pt containing particles formed by decomposition of volatile platinum oxide in the gas phase. http://pubs.sciepub.com/jmpc/5/1/2/jmpc-5-1-2.pdf speed cinematography optical spectroscopy combustion ignition instabilities cellular catalysis hydrogen
