Fuel Cell and Hydrogen
Safety Requirements
Do not attach or detach power cables when the fuel cell stack is turned on. Warranty is void if the fuel cell stack is dismantled or otherwise modified. Hydrogen is a colorless, odorless, and flammable substance. Always operate and store the fuel cell stacks and hydrogen storage canisters in an area with ample ventilation. Fuel cell systems should always be equipped with a highly accurate hydrogen sensor to detect any hydrogen that has escaped within the system or from the hydrogen storage canister. Please refer to the H-500 XP User Manual to see the full list of the safety requirements for the product.
