Electric drives based on unconventional energy sources are increasingly being used in various types of transport. One example of such a source is the PEM fuel cell. Typically, PEM cells are powered by pure hydrogen stored on board the transport vehicle and oxygen taken from the surrounding air. In conditions without air access, such as an underwater environment, there is a need to supply both pure hydrogen and oxygen to the fuel cell.This article presents the architecture of an electric power supply system based on a 6 kW PEM fuel cell, adapted for operation in air-independent conditions. Additionally, the article includes selected results of experimental tests of the designed and built power supply system.
SYSTEM OF ELECTRIC SUPPLY BASED ON PEM FUEL CELL TO WORK WITHOUT AIR ACCESS
More often, electric drives based on non-conventional sources of energy are used in different means of a transport. One of the example is PEM fuel cell. Usually
PEM cells are supplied by clean hydrogen stored on board of the mean of transport and oxygen achieved from an ambient air. In the case of conditions without an air access e.g. an underwater environment, it is necessary to deliver to fuel cell both clean hydrogen and oxygen.
In the paper, an architecture of a system of electric supply based on PEM fuel cell with 6 kW power, adopted to work without air access, is presented. Moreover, selected results of experimental research of designed and built supply system are included. (…)
