Bipolar plate of fuel element of round shape Proposed bipolar plate of a fuel element (FE) of round shape comprises separating plates, which have a middle area, in which channels are arranged by evolvents of the circumference, limiting the central area, besides, the length of the circumference, by which evolvents are built, is equal to the product of the number of channels and the pitch, and the pitch of channels is even along the length of the circumference, the central zone, which includes inner ends of evolvent channels and channel ribs of which on the plates are arranged so that during assembly they cross, forming flat central collectors, a peripheral circular zone, made of crossing channels and conical ledges, via which supply and drain of reagents and coolant are organised to external ends of appropriate evolvent channels. Separating plates along the periphery and a peripheral sealing edge have holes matching along the periphery, which during assembly of the FE battery form collector channels for supply of oxidant, fuel and coolant via horizontal channels to the peripheral circular area of separating plates and further to appropriate cavities and drain of reagents from them. |

Method to diagnose fuel element Invention relates to power engineering, in particular, to the system of fuel element diagnostics and diagnostics of other chemical sources of electric energy, and may be used in autonomous, reserve, aviation power plants. In the proposed method they measure voltage of a reference electrode, installed on one of working electrodes of the fuel element, and calculate the extent of its wear, and compare it with the value of the critical wear of the current source, afterwards they make a conclusion on suitability or unsuitability of further operation of the source of current. |
