# How to Activate a Fuel Cell Position
Follow the steps below to activate your Fuel Cell positions:

**Step 2: Select Lockup Amount and Confirm**
Make sure you are on the “Activate” tab on the Fuel Cells page. Choose your preferred activation cycle and click “Fuel Up”.
*Note: If it’s your first time activating Fuel Cell positions, click "Enable Contract" to grant H2 Finance permission to interact with your wallet on the transaction.*
**Step 3: Lock and Earn**
Enter the amount of $H2 tokens you want to commit and double-check the lockup duration. Click on “Activate” and then “Confirm” to open the Fuel Cell position. Finalize the transaction in your connected wallet. This action will lock your $H2 tokens in the vault for the specified period. Now, sit back and watch as your rewards power up steadily over time!
*Note: The APRs will vary based on Fuel Cell utilization. In general, the earlier and longer you lock your $H2 tokens, the higher the APR. The APR will lower as more tokens are locked across Fuel Cells.*
