Abstract: A method for measuring oxygen storage capacity of a catalyst sample containing ceria is provided to calculate the oxygen storage capacity of the catalyst sample accurately at a set temperature, by using a thermal conductivity sensor for outputting a resistance value signal corresponding to the change of hydrogen concentration. A resistance value signal of hydrogen and time data are stored while the hydrogen is supplied to a thermal conductivity sensor in a pulse type(S11). The thermal conductivity sensor outputs the resistance value signal correspondingly to concentration change of hydrogen. A catalyst sample is oxidized(S12). The supplied hydrogen is reacted with the catalyst sample, and the resistance value signal corresponding to the concentration change of hydrogen is outputted by using the thermal conductivity sensor after the reaction(S13). The resistance value signal is surface-integrated with respect to a time value until a reference time when the resistance value signal is continuously outputted in the same peak value, thereby calculating the final surface integral value(S14). The resistance value signal is surface-integrated with respect to the time value until the reference time by using the stored resistance value signal and time data, thereby calculating a comparative surface integral value(S15). The amount of hydrogen used in the catalyst sample is calculated by using the final surface integral value and the comparative surface integral value(S16). The oxygen storage capacity of the catalyst sample is calculated by using the amount of hydrogen used(S17).

Abstract: PURPOSE: A manufacturing method of a metal substrate is provided to prevent the flow of exhaust air from being formed in laminar flows and to improve the purifying efficiency of exhaust gas by adding a process of forming plural holes on a cell wall of a metal substrate to a manufacturing process of the metal substrate. CONSTITUTION: A process of forming plural holes on a basic material(12) is added between a process of corrugating the basic material and a process of rolling the corrugated basic material. The plural holes are formed on each cell(14) at an interval of 1-3cm, preferably 1.5-2cm. Then, the corrugated basic material is rolled and a metal outer case is brazed. A catalytic element is coated over the inside of the cells to manufacture a metal substrate(10) for purifying exhaust gas. Exhaust gas flows and forms turbulent or transient areas to a hole-formed area from the inlet. The exhaust gas flows and forms turbulent or transient areas to the next hole-formed area from the first hole-formed area. The exhaust gas forms a turbulent or transient area repeatedly by flowing through each cell of the metal substrate so that the exhaust gas is smoothly diffused through the cells to be purified by the catalytic element.
