Abstract

A method for metering electric power of fuel cell includes connecting fuel cell to a metering unit with electric power metering element and operation-treatment element, using said metering element to meter accumulated value of electric physical value outputted by fuel cell and using said operation-treatment element to obtain residual power value of fuel cell by calculation according electric physical value metered by said metering element.

Description

technical field [0001] The present invention relates to a fuel cell power metering method and its device, which particularly provides a metering unit for metering the residual fuel concentration or residual power of the fuel cell. Background technique [0002] A known fuel cell is a battery core that utilizes hydrogen-rich fuel (such as methanol) to perform an electrochemical reaction with oxygen fuel to output electricity. In the field of application of miniaturized fuel cells, it is necessary to let the user know when the fuel concentration is insufficient or the stock is insufficient and the fuel must be replenished. Therefore, it is necessary to detect the fuel level and fuel capacity in the fuel container. The general fuel container is provided to detect the fuel concentration and the fuel stock through the expensive metering sensor, which is quite uneconomical for a large number of portable electrical products that need to be used at present. [0003] Therefore, the i...
