Abstract
A fuel cell comprises a thermal dissipation structure whose connecting element (8) is a shape memory alloy highly conductive at high temperatures, but much less so at low temperatures, which allows the cell to heat up quicker and reach its performance level.
Claims8
Fuel cell comprising at least an oxidising agent assembly (1) of the fuel and a thermal connector connecting the assembly to a cold source, characterised in that the thermal connector comprises a connecting strip (8) in shape memory alloy which composes a hot state where it has a high thermal conductivity and a cold state where it has a low thermal conductivity.
Fuel cell according to any one of the previous claims, characterised in that the thermal connector has a pair of radiators (7) on both sides of the connecting strip (8).
Fuel cell according to any one of the previous claims, characterised in that the thermal connector is embedded at one end into a support (2) of the assembly (1).
