The power density of fuel cells is expected to double in the medium
The 114-kW fuel cell in the Toyota Mirai has a power density of 3.1 kW/l, one of the best scores of any of the fuel cells currently on the market. Due to their number and thickness, bipolar plates contribute a large share of the cell volume. A great deal of R&D is actively being carried out on this topic, and some of the results offer the hope of achieving a power density of 6 kW/l in the medium term.

TECH FOCUS: Continental’s turbocharger/catalyst integration yields greater efficiency
After exiting the cylinder head, the exhaust gases from the latest supercharged petrol engines pass through the turbocharger turbine and then through a 3-way catalytic converter. Their path must be as short as possible in order to limit heat loss and reduce the time required to initiate post-cleaning after a cold start. However, this proximity complicates the operation of the catalytic converter, which receives unstable gas flows of different temperatures and different lambda coefficients (oxygen content). Continental has developed a turbine outlet integrating a mixer internal to the catalyst and an overflow valve that does not interfere with the post-cleaning operation.
