Experimenting apparatus for fuel cell technology

An experimenting apparatus for fuel cell technology, comprising:

• a fuel cell having a fuel source and operating characteristics including a current range, a voltage range, and a power range;
• at least three and a maximum of 15 resistors having resistances selectively connected to said fuel cell and functioning as electrical loads, said resistances corresponding to expected operating loads of said fuel cell;
• a lamp and an electric motor selectively connected to said fuel cell as further electrical loads;
• an ammeter having a maximum of two measurement ranges corresponding to the power range, the voltage range and the current range of said fuel cell and connected to said fuel cell;
• a voltmeter having a maximum of two measurement ranges corresponding to the power range, the current range, and the voltage range of said fuel cell and connected to said fuel cell, said resistors, said ammeter and said voltmeter provided for an experimental determination of the operating characteristics of said fuel cell;
• a board having a rotary switch fitted on said board, said electrical loads, said further electrical loads and said ammeter being disposed on said board and electrically
• connected to one another, said electrical loads and said further electrical loads connected to said rotary switch and selectively connected to said fuel cell through said rotary switch;
• and
• said board having a short-circuit terminal and an open-circuit terminal connected to said rotary switch, said fuel cell to be switched to said short-circuited terminal through said rotary switch for testing a short-circuit condition, and said fuel cell to be switched to said open-circuit terminal being open contacts for measuring a no-load voltage.
