Alfred Pennyworth to reject Alfred. (The name "Pennyworth" was first used for Alfred in 1969 and thereafter it has been assumed that his father was named Jarvis Pennyworth; as it is customary for British domestic servants to be called by surname it might have been implied on Alfred's introduction that Jarvis was the surname he shared with his father; the surname "Beagle" was explicitly used for Alfred starting in 1945 and on the introduction of "Pennyworth" this is treated as having always been their name by retcon). Initially, Alfred discovered their identities by accident; while fighting a burglar in "Batman" #16 (Alfred's
Butler–Volmer equation the surface is equal to that in the bulk. There are two limiting cases of the Butler–Volmer equation: where formula_21 and formula_22 are constants (for a given reaction and temperature) and are called the Tafel equation constants. The theoretical values of the Tafel equation constants are different for the cathodic and anodic processes. However, the Tafel slope formula_22 can be defined as: where formula_25 is the faradaic current, expressed as formula_26, being formula_27 and formula_28 the cathodic and anodic partial currents, respectively. Butler–Volmer equation The Butler–Volmer equation (named after John Alfred Valentine Butler and Max Volmer), also known as Erdey-Grúz–Volmer
