Abstract The concentration and potential gradients across an electrolyte-containing membrane of the hydrogen-oxygen fuel cell have been calculated taking into account the following processes: diffusion of all solution components, ion migration in the electric field, permeation flux of the solution, external water vapour flows, water vapour transport in gas bubbles. A theory of the self-regulation of water removal has been developed, which takes account of the mass exchange conditions in the membrane and in the whole fuel cell, as well as the concepts of the buffer capacity of a fuel cell with a capillary membrane. The self-regulation of water removal during changes of the current or during changes of parameters influencing the rate of water removal, as well as the self-regulation in the case of a non-uniform process distribution over the electrode surface have been considered.
