NEW YORK (CNNMoney.com) -- Gerri Willis answers reader's questions.

Question 1. If you are currently on a payment plan with the IRS and all payments are current, will the IRS keep your stimulus check?

Yes. The IRS says that if you owe taxes the money will be used to cover you debt.

Even though you're current on your payments, you still owe money to the government. And if you have delinquent student loan debt, missed child support payments or you owe back taxes, you probably won't see your stimulus check either if the amount you owe is more than your rebate check.

If you have any questions, or you want more information you can contact the IRS at 1-800-829-1040.

And don't forget, those checks are going out sooner than expected the President announced today. If you have direct deposit, you could get your check as early as Monday.

Question 2. I just got a small settlement and it will pay off my credit card in full. However my FICO is 734 and I want it to rise! Do I pay it off or just pay some of the balance and put the rest in savings?

If you want to improve your credit score, put the money toward paying off your credit card.

Your credit card interest rate is much higher than what you would make if you put your money into a savings account.

Once you've paid off your debt, your next priority should be to boost your savings. To find high yielding bank accounts, go to bankrate.com.

Question 3. How do hydrogen fuel cell cars differ from hybrids?

Hybrids use both an electric motor and a traditional gasoline motor.

On the other hand, hydrogen fuel cell cars use hydrogen as its fuel says Jon Linkov of Consumer Reports. That hydrogen then produces electricity that powers the car.

In a fuel cell car, there are no emissions, which is not true with the hybrid. However, there are only a few prototypes of hydrogen fuel cell cars out there and it could take another ten years to get a full rollout of hydrogen fuel stations according to Linkov.

Saving gas is a matter of proper behavior behind the wheel. Increase your following distance and use your brakes when really necessary.
