METHOD FOR CONTROLLING THE METHANOL CONCENTRATION IN DIRECT METHANOL FUEL CELLS |
摘要 |
The invention relates to a direct methanol fuel cell and to a method for controlling the methanol concentration without requiring the provision of additional methanol concentration sensors (47). Instead, the current-voltage characteristic curves of the fuel cell (40) are sampled using small variations of the system variables current I and methanol concentration M, and information used for controlling is obtained therefrom. In systems possessing an electrical buffer (49), a connected consumer is supplied without interruption despite the abandonment, as described by the invention, of the optimal operating point of the fuel cell. |
