As no conversion is without some losses (the laws of thermodynamics assures this is the case) there will be heat loss, transmission losses, wear and tare on the equipment etc. There will be other losses/waste from the manufacturing of the equipment and the recycling of the equipment when it is no longer in service.
When hydrogen is burned in oxygen, water is produced. I'm not sure if that's what you were looking for or not. You can use the heat generated to produce electricity, but it's not really "waste" in the normal sense of the word.
You probably mean a fuel cell, which is a device for combining a fuel (usually hydrogen) with an oxidizer (usually oxygen), creating electricity (and some waste heat).

Hydrogen, Oxygen, Potassium, some others
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
Hydrogen is an excellent fuel because when it combusts inside the car engine the only waste products passed through the exhaust pipe are pure water and some heat. However the costs of producing hydrogen are high, the most efficient way probably being the use of water from dams speeding down pipes to turbines which produce electricity. If the hydrogen is then produced by electrolysing water (H2o), thus producing hydrogen separated from the oxygen, this uses lots of electrical energy. So hydrogen powered cars do not at present save money, but they do reduce pollution of the air.

Because when hydrogen is burnt in oxygen - the only waste product is water !
To get Hydrogen as a fuel to be used in electric vehicles, the hydrogen combines with oxygen giving of 2 electrons which powers the application. The waste product is H20 (water!). If you want a simple yes or no, then the answer is Yes, because you are converting Hydrogen into Water to produce electricity.
