Abstract

An activation apparatus of a fuel cell stack is provided. The activation apparatus of a fuel cell stack which is provided to perform activation and evaluate performance of the fuel cell stack while the fuel cell stack enters a frame. The apparatus includes an output cable connecting unit that is movably installed back and forth along a side direction of the fuel cell stack in a motor operated manner, and is configured to connect an output cable with the fuel cell stack.

First claim

What is claimed is:

1. An activation apparatus of a fuel cell stack for performing activating and evaluating performance of the fuel cell stack while the fuel cell stack enters a frame, the apparatus comprising:
an output cable connecting unit movably installed back and forth along a side direction of the fuel cell stack in a motor operated manner, and configured to connect an output cable with the fuel cell stack,
wherein the output cable connecting unit, includes:
a moving body movably installed back and forth along a side direction of the fuel cell stack by an actuator, and
a pair of connecting terminal sets elastically installed on the moving body and connected to an output terminal of the fuel cell stack,

wherein the connecting terminal set includes:
a cable connecting member fixedly installed to the moving body and connected to electric load equipment via an output cable;
a terminal rod that protrudes outwardly from the cable connecting member and is movably installed back and forth in a side direction of the fuel cell stack, wherein a connecting terminal is installed at the protruding end of the terminal rod; and
a spring installed inside of the cable connecting member and configured to exert an elastic force to the terminal rod.

2. The activation apparatus of a fuel cell stack of claim 1 , wherein on the moving body, a pair of attachers are installed to support a side surface of the fuel cell stack.

3. The activation apparatus of a fuel cell stack of claim 2 , wherein the attachers have a block shape and are made of a rubber material.

4. The activation apparatus of a fuel cell stack of claim 1 , wherein the connecting terminal is inserted into a terminal receptacle disposed at a side surface of the fuel cell stack, and forms a tapered outer circumference.

5. The activation apparatus of a fuel cell stack of claim 4 , wherein a supporting member of a disk shape that supports the output terminal of the fuel cell stack is installed at the end of the protrusion of the terminal rod.

6. The activation apparatus of a fuel cell stack of claim 1 , wherein the actuator includes an operating cylinder connected to the moving body.

7. The activation apparatus of a fuel cell stack of claim 6 , wherein the moving body is movably installed back and forth to the frame by a pair of guide bars.

8. The activation apparatus of a fuel cell stack of claim 7 , wherein the guide bar is inserted into a pair of supporting blocks disposed on the frame and is configured to guide a movement of the moving body.

9. The activation apparatus of a fuel cell stack of claim 1 , wherein the output cable connecting unit connects a positive (+) cable of electric load equipment to a positive (+) output terminal disposed at a side of the fuel cell stack.

10. The activation apparatus of a fuel cell stack of claim 9 , wherein a negative (−) output cable of electric load equipment is connected to a negative (−) output terminal disposed at another side of the fuel cell stack using a fluid supply tube connecting unit to supply fluid to the fuel cell stack.

11. The activation apparatus of a fuel cell stack of claim 10 , wherein the fluid supply tube connecting unit includes:
a moving body that is movably installed to the frame back and forth in the other side direction of the fuel cell stack by an actuator.
