The 60-year-old Frenchman has been suspended along with Fifa president Sepp Blatter and secretary general Jerome Valcke. They deny wrongdoing.
Platini, a Fifa vice-president, is the Football Association's preference to succeed Blatter at Fifa.
The French FA wants the Court of Arbitration for Sport to intervene to ensure Platini can stand for election.
Fifa's ethics committee began its investigation after the Swiss attorney general opened criminal proceedings against Blatter in September.
He is accused of signing a contract "unfavourable" to Fifa and making a "disloyal payment" to Platini.
The ethics committee also opened an inquiry into Platini over the 2m euros (£1.35m) payment, which was made nine years after the former France footballer carried out consultation work for Blatter.
Fifa will hold an emergency meeting on 20 October in Zurich to discuss February's presidential election, at which a successor to Blatter will be chosen.
Platini, Uefa's president since 2007, has been backed by South America's football confederation following his suspension.
Conmebol said he should be regarded as innocent until proven guilty.
The French Football Federation is expecting a decision from Fifa's appeal committee within eight days.
"The FFF has adopted the principle of an appeal if the decision of the Fifa appeal committee does not go Michel Platini's way," said a FFF spokesman.
Blatter, 79, won a fifth consecutive presidential election in May but announced he would be stepping down just days later following the launch of two investigations into Fifa by United States and Swiss authorities.
Platini is one of the favourites to replace him and still plans to stand. He has the full backing of Uefa, which is holding an emergency meeting next week.

Rowe, Team Sky's road captain, broke a rib in a crash on the opening stage but rode on to support team leader Froome.
The 27-year-old finished as lanterne rouge, an honour for the rider in last place on general classification, noting the sacrifice of their own ambitions to help their team's bid for yellow.
"That's incredible," Brailsford said of Rowe's effort after breaking his rib.
"They're so robust, these guys, and he went down really hard.
"He caught his rib on the pavement as he went into it and probably did more damage than we originally thought.
"He was in a lot of pain but he pulled through and he's so good as a road captain - he communicates so well.
"We would have been in big trouble without him actually so it was great that he pulled through."
Froome's winning time of 86 hours, 20 minutes and 55 seconds saw him finish 54 seconds ahead of Rigoberto Uran in second place.
Rowe ended the race four hours, 35 minutes and 52 seconds behind Froome as he toiled in order to help the Team Sky leader claim his third successive title.
The Welshman finished 167th in the general classification, more than three minutes adrift of second-from-bottom Tom Leezer.
But the lanterne rouge is something of a badge of honour for Tour cyclists, with Rowe spending much of the 2017 race chasing down breakaways at the front, then bringing up the rear of the peloton having spent all his energy in Froome's cause.
