Method and device for determining a concentration of fluidic fuels for use in fuel cells |
摘要 |
The method determines the fuel concentration in fluidic fuels for fuel cells, and in particular the alcohol concentration in an alcohol/water mixture for fuel cells operated with the mixture, such as direct methanol fuel cells. The alcohol/water mixture is passed through a heating section at a constant flow rate, a known quantity of heat is supplied to the mixture, the temperature difference between the entry and exit of the heating section is measured and the alcohol concentration is determined therefrom.
