Hydrogen Fuel Cell

A hydrogen fuel cell with a power rating of 1200W is required for CH459. The fuel cell should operate using a standard hydrogen gas cylinder and oxygen taken from the air. It should be able to connect to a 24 battery volt system for the battery hybridization. The generated power should be able to be used by a dummy load and a bank of 100W – 1000W light bulbs.

The contents of the fuel cell lab setup should include

1. Fuel Cell Module:

a. Performance: The rated power should be 1200W. The nominal voltage varying between 20-36VDC. There should be a maximum output current of 60A and a net efficiency (at rated power) of 50%.

b. Fuel: The module should utilize hydrogen with a minimum purity of 99.95% with a consumption 15 standard liters per minute.

c. Coolant: Forced Air with a flow rate at rated power of 335 m3/hr.

d. The system should operate between 5-40OC (41-104OF).

e. There should a minimum of 40 cells stack. With a hydrogen gas pressure reducer to 300-350mbar. There should a pressure sensor for the stack.

f. The system must be connectable and controllable by an electronic load.

g. The system must be compatible with a laptop to monitor the power, voltage amperage, temperature, hydrogen consumed, etc.

2. 24 DC voltage convertor

a. The converter should be compatible with the fuel cell module and deliver a steady output voltage of 24V and should enable battery hybridization of the fuel cell system. There should be a maximum output current of 55 A. The output voltage would vary between 0-32V. The rated output should be 1200W and the input voltage should vary between 16-50V. An efficiency of more than 95% is expected.

b. Parameterization via PC software.

3. Software that communicates between the hardware and a Windows OS

a. The function of the software is to switch the units to the various operating modes and to visualize all relevant operating parameter. There should also be a mechanism for the various parameters to be saved.

b. The software should be compatible with Windows OS both 32 bit and 64 bit.

4. Power Supply Unit

a. This should help start up the fuel cell module by acting as a AC Adaptor

b. The output voltage should be 24VDC, current 5.2AdC and power 150W.

5. 24V battery Set for battery hybridrization

a. They should be two Lead Gel Batteries at 18A.

6. DC/AC invertor for supply for AC Voltage Consumers

a. This inverter should operate the electronic load requiring DC/AC input.

7. Hydrogen gas Flow meter

a. This should enable the exact measurement of the current hydrogen consumption. The measuring range should be up to 25standard liters per minute operating between 0-50OC (32F to 122F) with an accuracy of ±1.5% of the full scale.
