Test bench for DMFC fuel cell and methanol electrolyzer with climate chamber

Test bench designed and built by PiCoHiMA with a climatic chamber making it possible to regulate the working temperature of the DMFC or the methanol electrolyser up to 80°C and to test these devices with maximum current voltage and intensity of 10 V and 10 A, respectively. It consists of a cylinder of O2 and another of N2, both gases compressed at 200 bars with a pressure reduction valve, a Bronkhorst EL-FLOW Select O2/N2 mass flow controller, a humidifier (two wash bottles connected in series, containing Milli-Q grade water), a Bronkhorst EL-PRESS pressure controller, a tank of methanol solution, a Jasco PU-4180 pump, a Julabo F33-EH circulation cryothermostat, a 120 mm fan, a DC power source for the Ayscom N6700B fan, an Ayscom 6 1/2 digit Truevolt DMM multimeter, an Autolab PGSTAT128N potentiostat-galvanostat with FRA32M and BOOSTER10A modules, a computer with an Intel Core i7 processor, and two methacrylate urns with a heat exchanger.
