METHOD AND APPARATUS FOR MEASURING CRITICAL AMOUNT OF CARBON DEPOSIT IN CATALYST

摘要

PURPOSE: A device and a method for measuring the critical deposition of the carbon of a catalyst are provided to quantitatively measure the extent of the penetration of the carbon possible to adversely affect the performance and the durability of the catalyst utilized in a fuel cell on a real time basis. CONSTITUTION: A device for measuring the critical deposition of the carbon of a catalyst (1) includes an electric resistance measuring device and a weight measuring device (5). The electric resistance measuring device measures a change in electric resistance due to the carbon deposition in which carbon is deposited. The weight measuring device measures an increase in the weight of the catalyst, thereby measuring the deposition of the critical carbon of the catalyst.
