At the upcoming Paris Motor Show, PSA Peugeot Citroën will unveil the 207 Epure Coupé / Cabriolet concept car—a new fuel-cell hybrid using a PSA-developed fuel-cell stack.
The 207 Epure is an application of the development work PSA has undertaken with the French CEA (Commissariat à l’Energie Atomique—Atomic Energy Commission) on a new design of compact fuel cell that offers improved power output, energy efficiency and packaging: the GENEPAC (GENérateur Electrique à Pile A Combustible). (Earlier post.)
GENEPAC uses a modular design, consisting of one, two, or four PEM stack modules which are connected to a central fluid distributor. For the 207 Epure, PSA used a 20kW GENEPAC stack consisting of two modules.
A single electric drive motor provides 40 kW of power (peak output of 70 kW) and 180 Nm (133 lb-ft) of torque. A lithium-ion battery provides up to 50 kW of power. Five 15-liter cylinders hold a total of 3 kg of gaseous hydrogen compressed to 700 bar.
The tanks and battery are located at the bottom of the vehicle’s trunk, which frees up the two rear seats, does not affect the operation of the retractable roof mechanism and leaves part of the trunk available for use in the coupé position.
The Epure has a range of 218 miles (350 km), with a top speed of 81 mph (130 kph). It accelerates from 0-62 mph in 15 seconds.
