In many medical systems a reliable energy sources play an important role. In the case of failure of external energy system, the local electrical supply has to be activated. Such electrical sources should be environmentally friendly, infallible and easy in usage. The fuel cells using hydrogen as an energy source fulfil these conditions. Numerical modelling of such electrical sources is the primary aim of this publication. Influence of the distribution of temperature on the current density and electric potential fields in electrode of the PEM fuel cell is thoroughly considered. The problem is stated as coupled field problem, where partial differential equations describing mass transport are coupled with Laplace equations describing electric potential and temperature distribution. At the end some illustrative example is given
