A FUEL CELL UNIT

摘要

This invention relates to fuel cell unit for use in aggregating fuel cells, particularly useful for use when fuel cells are connected in parallel. Improving the management of fuel cell outputs across a plurality of aggregated fuel cells improves efficiency of the fuel cells. The invention relates to a fuel cell unit comprising a fuel cell and a regulating voltage converter, and further relates to a fuel cell module comprising a plurality of fuel cell units connected in parallel.

主权项

1. A fuel cell unit adapted to connect to a positive load rail and a negative load rail, suitable for being one of a number connected in parallel to the positive load rail and the negative load rail, the fuel cell unit comprising a fuel cell, having a fuel cell output voltage presented between a positive fuel cell output terminal and a negative fuel cell output terminal, and a regulating voltage converter having a DC converter output voltage presented across a positive converter output terminal and a negative converter output terminal and an input adapted to be driven;
the regulating voltage converter being arranged so that the input is driven by the fuel cell output voltage in series with the converter output voltage; and the converter output voltage combines with the fuel cell output voltage such that the voltage across the fuel cell and the regulating voltage converter is the same as the voltage across the positive load rail and negative load rail.
