| 摘要 |
This invention relates to fuel cells. A fuel cell (10) defines a space (11) having an air/ethanol inlet (12) and an outlet source (13). The operative part of the fuel cell, (14), includes a pvc substrate (15), a working electrode (16) and a counter electrode (17). A working electrode current collector (20) extends over the working electrode (16), whilst a counter electrode current collector (21) extends across the counter electrode (17). The electrode current collectors may be formed from tantalum. At least one of the current collector electrodes (20, 21) are non-conformably depressed into their associated electrode to define a channel for containing electrolyte whereby charge can be transferred to the current collector by ionic exchange. |
