Abstract: Enhanced security is provided for a transaction involving a customer using a financial device associated with a financial account. Information regarding an authorized user of the financial account is received and stored in a storage system prior to the transaction. The information is capable of being used by a person to identify the authorized user. The stored information is provided to a merchant such that the information can be used by a person to determine whether or not the customer and the authorized user are the same before the transaction is completed. If the customer and the authorized user are determined to be the same, then the transaction is completed.

Abstract: A fuel cell system that employs a purge valve, an accumulator and a bleed valve for selectively purging and bleeding anode exhaust gas. When the purge valve is opened, the anode exhaust gas purges to the accumulator where it is collected. The bleed valve provides a controlled release of the anode exhaust gas from the accumulator that allows the concentration of hydrogen bled from the accumulator to remain below its combustible limit. In one embodiment, the purged anode exhaust gas is combined with the cathode exhaust gas and released to atmosphere. In another embodiment, the purged anode exhaust gas is combined with a cathode input gas. In another embodiment, the purged anode exhaust gas is combined with an anode input gas.
