Process gas e.g. anode gas, supplying method for testing e.g. catalyzer of fuel cell, involves mixing gases with different temperature levels, and supplying partial flow of gases at temperature within range of room temperature

摘要

The method involves adjusting temperature and mass flow of process gases e.g. anode and cathode gas, independent from each other, and feeding the gases into a test stand of cell components e.g. reformer, of a fuel cell (2). The gases with different temperature levels are mixed using gas injectors (3a-3e, 4a-4c). A partial flow of the gases at a temperature i.e. 25 degree Celsius, within a range of a room temperature, is supplied to the injectors. Another partial flow of the gases at a high temperature within a range between 100 and 950 degree Celsius is supplied to the injectors. An independent claim is also included for a device for supplying a process gas.
