Characteristics Of Small Formic Acid Fuel Cells. The external characteristics of a fuel cell the diagram presented in fig. 2 has been divided into three areas. three kinds of losses can be distinguished: loss of activation, losses connected with the decrease of pressure due to inner resistance of a cell and weight losses. the decrease of pressure in area i is the result of so called activation losses. these are the losses of the energy which, while the power-generation characteristics of the flow fuel cell, generally speaking, were improved on the high-pressure operation, the power-generation and the crossover characteristics of the dead-end fuel cell were examined using the mea of no. 2 when the cell pressure was changed..
