Fuel cell system has pressure increasing pump and cooler in line leading from liquid fuel container to fuel cells, nozzle in line from fuel cell back to container

摘要

The direct fuel cell system has a fuel container (14), e.g. for methanol, a line (12) for delivering liquid fuel to the fuel cells (10), a further line (18) leading back into the container, a nozzle in the further line, a pressure increasing pump (16) in the line leading from the container to the fuel cells and a cooler (36) before or after the pump in this line.
